But what Mythos is doing today, in Chet’ s eyes, is making Linus’ law from three decades actually come true.“ Humans can only look at a hundred thousand permutations of memory misuse before they get bored,” he says.“ The machine doesn’ t get bored. Mythos doesn’ t get bored. It will keep looking to make sure there aren’ t any vulnerabilities and I’ m kind of excited about that.”
The tech debts we owe According to Chet, what Mythos is finding are“ tech debts”, which he describes as“ those little mistakes we made along the way that nobody could be bothered to go back and find or fix”.
With Mythos in the loop, these debts are being paid back as infrastructure is being broken and rebuilt, more hardened

Sophos than ever, making it even more difficult to exploit. In the short term, however, things are less than ideal.
“ It’ s going to be painful for a while,” he admits, weighing the huge amount of effort it takes for humans who have to fix and validate these flaws.
IT teams are already behind on patching as it is, and with new patches rolling in faster, the situation puts a lot of stress on engineering teams.
These frontier models may also make the internet a more dangerous place, leading to internet-facing devices becoming more vulnerable.“ As an industry we need to evolve in quite a few different ways to make this less painful,” Chet says.
An example of this evolution would be to make internet-facing equipment self patching, so humans need not worry about disruptions or piling loads of patches.
