The problem with that, at least in the case of Rosetta, is that the QuickTransit technology underlying it got bought by IBM and disappeared from the open market, so doing that trick again would be...a moderate time+cost sink.

Wiki for QuickTransit seems to think that a number of prominent people from Transitive hopped to ARM and Apple (which might be telling, given the claims of the original post), but has no citations.

Eh, JITs aren't the most complicated things on the planet. There's plenty of people who can do it outside of QuickTransit. Like, look inside most emulators.

Given that Apple is writing compilers and designing chips, on-the-fly recompilation shouldn't be a big problem for them.
