These might look like separate stories, but they share one common thread: AI has sharply cut the cost of understanding old code, as long as something can check its work.

So yes, AI is a big part of it, but it's not the whole story. Three things converged.

TL;DR: why this is happening now

  • Years of human groundwork were already in place
    Many of today's headlines sit on decompilations volunteers spent five or...
