"in 6–12 months such a swarm could be capable of taking over the entire internet with a persistent botnet"
Maybe, maybe not. If it does, the internet (really: software and operating systems) obviously need some improvement and we should do so. If the bugs are there, they will be found, one way or another regardless of some LLM. What a great opportunity for a renaissance.
Anyone else remember the doomerism around Y2K? Int overflows because of epoch seconds? This is that.
