    Season 3: Episode 9 - The Leadership Characteristics Every Senior Technologist Should Steal

    The CTO Lens Podcast is back with Episode 9 of Season 3, and this week David is fresh from his daughter's wedding, throwing caution to the wind and thinking about a curry. Normal service has resumed. This episode covers Andy Burnham's first day as Prime Minister and the rumoured scrapping of the Department for Science, Innovation and Technology - and whether that's actually as bad as the headline suggests. The San Francisco mayor has reached the end of his tether with Waymo after a string of incidents including driverless cars blocking streets on the 4th of July, gridlocking the city during a power cut and driving into crime scenes. China's AI startup Moonshot launches Kimi K3 with 2.8 trillion parameters and challenges every major American AI firm. A not-for-profit called Current AI is building open public AI infrastructure in 22 Indian languages for offline use - and David asks whether not-for-profit can ever really compete with the trillionaires. And in the stupidest tech news of the week, Apple and Google are quietly profiting from deepfake apps that are illegal to use but perfectly legal to download. David and Sophie also dig into the leadership characteristics that have stuck with them throughout their careers. Admitting when you don't know something. Finding inspiration in the people above you. Staying calm when everything breaks at three in the morning. Balancing humility with confidence - a word David cannot stand. Empowering your team without becoming a clone factory. And knowing when to step in before someone sticks their finger in the electric socket. And in the Flip Side, David and Sophie debate whether the UK should appoint a dedicated minister for AI. David says no. Sophie says yes. David flips. They land somewhere sensible, as is becoming tradition.

    Season 3: Episode 8 - Life After Being a CTO

    The CTO Lens Podcast is back with Episode 8 of Season 3, and this week David and Sophie are recording through what appears to be the hottest summer on record - though neither of them has air conditioning, so they're making do. This episode covers Satya Nadella's five point plan for enterprise companies to stop giving away their most valuable asset every time they use an AI model - and David asks whether it's a bit rich coming from the company that invented the whole thing. Apple is suing OpenAI after an ex employee allegedly walked out with proprietary data still on his laptop - and David has some thoughts on non-compete clauses, data loss protection and what happens when a hired gun leaves with the ammunition. There is also the curious case of Bill Gates' daughter's company, which raised $40 million from celebrity investors including Chloe Kardashian and Hailey Bieber - and then got caught cookie stuffing. David recommends getting an enterprise architect. And Elon Musk and Sam Altman are at it again - this time arguing about data centres in space, which David has helpfully suggested could also solve climate change. Patent pending. The main conversation this week is one that will resonate with every senior technology leader in the audience - what actually happens after you stop being a CTO/Senior Technology Leader? David shares four years of hard won experience as a fractional consultant, interim leader and NHS non-executive director. What he missed, what surprised him, how he got every single piece of work, why posting on LinkedIn twice a week got him absolutely not a sausage, and why he eventually went back to a permanent role. Sophie asks the hard questions. David gives good testimony. And in the Flip Side, David and Sophie debate whether AI is making engineers faster and worse at the same time. David argues yes. Sophie argues no. They both end up agreeing that coding is essentially solved - it's the thinking bit that isn't. Watch out for your acceleration whiplash.

    Season 3: Episode 7 - Which C-Suite Role Is AI Coming for First?

    The CTO Lens Podcast is back with Episode 7 of Season 3, and David and Sophie are recording in what appears to be the hottest summer on record - and as it turns out, that's actually relevant to the news agenda. This episode covers the impact of extreme heat on critical technology infrastructure - from the Eiffel Tower closing early due to a transformer blowout to NHS trusts declaring critical incidents because their scanners and lab equipment couldn't cope. Solar panels, it turns out, are also struggling in the heat. David has a request for every technology leader listening. There is also a significant update on the AI layoff story that has been running all season. Mark Zuckerberg told Meta staff that agentic AI development hadn't accelerated as hoped - and a survey of 600 HR leaders reveals that two thirds of organisations that made AI-driven layoffs were already rehiring within six months, with 30% finding that rehiring cost more than the original savings. David and Sophie ask what tech leaders should take from this. Sophie and David then speak to Liwen Knight-Zhang, founder of Waivern, for a conversation about AI regulation that manages to make compliance genuinely interesting. Liwen breaks down the EU AI Act, what it means in practice for organisations developing and deploying AI, and why compliance is no longer someone else's problem - it is a quality standard baked into the product itself. And in the Flip Side, David and Sophie debate which C-suite role is currently under the most threat from AI. David makes the case for the CMO. Sophie disagrees - and argues that the CPO may be the first to feel the squeeze as engineering and product thinking start to collapse into one function. It gets lively.

    Season 3: Episode 6 - Human in the Lead - Rethinking AI, Teams and the Consulting Model

    The CTO Lens Podcast is back with Episode 6 of Season 3, and David and Sophie are both back in the hot seat - tanned, reunited and ready to dig into a packed agenda. This episode covers Trump's threat to impose a 100% tariff on any European country that introduces a digital services tax on American tech giants - and asks whether it's time for tech leaders to start buying homegrown. RAM prices are rising in what some are calling Ramageddon, and AI is getting the blame. Ford has quietly hired back the human engineers it replaced with AI after the robots failed to match their skills - and David has some advice for any engineer worried about their job. Anthropic's Mythos gets another update, with more than 100 US government agencies now granted access. OpenAI's Sam Altman launches Patch the Planet to fix the open source vulnerabilities that Anthropic's models were built to expose. And Europe gets its own answer to MANGOES - it's called BRIOCHE, and Sophie is very much on board with that. Sophie also sits down with Amul Batra, co-founder of Northcoders and MD of Counter, for a genuinely fascinating conversation about why the standard consulting model does its clients a disservice - and what a better one looks like. Amul also makes a compelling case for why junior developers aren't disappearing, they're just changing - and introduces a phrase that might be the most important reframe in AI adoption right now: not human in the loop, but human in the lead. And in the Flip Side, David and Sophie ask the question every tech leader should be sitting with right now - in five years, what will companies realise they completely got wrong about building tech teams? Sophie argues for wholesale organisational redesign. David argues for not throwing the mainframe out with the bathwater. They meet somewhere in the middle, as is tradition.

    Season 3: Episode 5 - How to Build Sustainability in IT: Embracing Opportunities and Driving Value

    The CTO Lens Podcast is back, and this week Sophie is taking a well-earned break. David is joined by the returning Mal Minhas for a packed episode of news, a fascinating guest conversation and a debut Flip Side argument that ends - as these things often do - somewhere in the middle. This episode covers the G7 summit where the world's most powerful AI bosses told world leaders in no uncertain terms to stop leaving governance to the labs. The US government bans Anthropic from releasing its newest and most powerful models, citing national security concerns - and David wonders if it's just very effective marketing. Apple launches Siri AI and quietly reminds everyone why you should never count them out. Google halves the price of its AI subscription. And Keir Starmer resigns as Prime Minister, which raises the not entirely trivial question of what a new government means for UK tech. David and Mal are also joined by Allard Pheifer, Global Sustainability Lead at CHG Meridian, for a conversation that will make you rethink everything you assumed about sustainability in IT. Allard reframes it entirely - not as a compliance burden but as a value creation opportunity - and shares how he built an AI powered tool that lets account managers build a full business case for a customer in under sixty seconds. And in the Flip Side, David and Mal debate whether the biggest mistake technology leaders make is hiring for technical excellence - and whether character should come before code. They disagree, then agree, then meet somewhere in the middle. As is tradition.

    Season 3: Episode 4 - Women in AI: The Biggest Myths, a Deportation & Why the Human Has to Come Back

    The CTO Lens Podcast does something a little different this week. David is away, and Sophie has taken the opportunity to bring together three brilliant women working at the sharp end of AI for a conversation that is honest, practical and long overdue. Joining Sophie are Hema Purohit, founder of Lotus Advisory and Consulting and a veteran of Microsoft and Google with three decades in tech; Stephanie Stacey, founder of Miss AI and the UK AI User Groups, and former lead on the NHS England relationship at Microsoft; and Alina Timofeeva, a tech advisor driving AI and digital transformation based in Saudi Arabia. Together they cover the biggest myths people confidently repeat about AI, why Europe's organisations are losing out by chasing shiny tools instead of building foundations, where real leverage is starting to emerge, and the skills that will actually matter in the next five years. There is also a conversation about power, capital and ownership - and whether women should be joining AI companies, owning AI infrastructure, or something else entirely. It is a wide ranging, refreshingly candid discussion - with a story about an AI-induced deportation that you will not hear anywhere else.

    Season 3: Episode 3 - Is the Job Market for Senior Technology Leaders Broken?

    The CTO Lens Podcast is back with Episode 3 of Season 3, and this week David and Sophie have a packed agenda - news, a brilliant guest and a Flip Side debate that gets a little complicated when Sophie switches sides mid-argument. This episode covers Meta's customer support chatbot being exploited to steal Instagram accounts - and what every tech leader should take from it about deploying agents without really knowing what they can do. Europe's AI startups face an existential reckoning as token costs rise. OpenAI expands beyond developers to target knowledge workers. ChatGPT confirms ads are coming. An Anthropic co-founder reveals 80% of Claude's code was written by Claude itself - and 100% is possible within two years. A company backed by Sam Altman raises half a billion to bring nuclear fusion to the grid by 2028. And the silliest news of the week - a burglar uses a Waymo as a getaway car to steal yoga clothes in San Francisco, and the police still haven't caught them. David and Sophie also sit down with Simon Hudson, fractional CTO and long-time London Tech Leaders community member, for a frank conversation about the senior tech leadership job market - ageism, inflated CTO titles, why networks matter more than ever, and what experience really means when AI claims to have all the answers. And in The Flip Side, David and Sophie debate whether the rising cost of intelligence should be passed on to consumers or absorbed as the cost of doing business. Sophie argues for. David folds his arms and says no. Sophie then crosses the floor mid-debate - and David declares victory.

    Season 3: Episode 2 - "The Best Engineering Leaders of the Next Decade Won't Come from Engineering"

    The CTO Lens Podcast is back with another packed episode. David's fresh from a stag weekend involving combat archery, a giant inflatable and some questionable social media evidence, while Sophie's been spotting baby moorhens. Normal service has resumed. This episode covers NVIDIA's new AI chip for personal computers - and what that means for every CTO's laptop refresh plan. King's College London becomes the first UK academic team to access Google's quantum chip Willow, and David and Sophie ask whether quantum computing is finally becoming real or still a solution searching for a problem. GitHub Copilot switches to token-based pricing and some developers are seeing costs jump from $50 to $3,000 a month overnight. There's also a deep dive into token maxing - including Amazon's ill-fated internal AI leaderboard that had to be shut down - humanoid robots arriving on BMW's factory floor with a three-minute battery break, and the growing NEET crisis as automation starts to reshape the jobs market for young people. Plus a quick IPO update on SpaceX's surprise government contract and Anthropic's $65 billion raise ahead of a potential public float. Sophie sits down with Tris Bates, Head of Mobile Engineering at New Day and driving force behind NS London - Europe's largest Apple developer community - for a fascinating conversation about what AI tools are actually doing to mobile engineering in practice, why everyone wants an app, and why seeing through walls using WiFi might not be as far off as you think. And in this week's Flip Side, David and Sophie debate whether the best engineering leaders of the next decade won't come from engineering at all. David argues for the motion. Sophie dismantles him. David awards her a 60-40 victory and hints he might deserve a pay rise.
