    The Future

    After 283 episodes, this will be the final episode of the DAY[0] podcast. We started the podcast on a hopeful note in the days following Ghidra's release. Now, to end it off we've got another discussion about how we see the future of vulnerability research and exploit development going. We recorded this episode before all the hype around "Mythos" and Project Glasswing so it doesn't play into our commentary here. Thank you all for the support over the last seven years. Good luck and happy hacking!
