It's more like JITs got good.

I never understood why AOT never took off for Java. The write once run anywhere quickly faded as an argument, the number of platforms that a software package needs to support is rather small.

Because developers don't like to pay for tools.

It is now getting adopted because GraalVM and OpenJ9 are available for free.

Also while not being proper Java, Android does AOT since version 5, mixed JIT/AOT since version 7.

EDIT: Fixed the sentence regarding Android versions.

Developers pay for tools gladly when the pricing model isn’t based on how much money you’re making.

I’m happy to drop a fixed 200e/mo on Claude but I’d never sign paperwork that required us to track user installs and deliver $0.02 per install to someone

I think what they do is correct. We also need to get paid this way.
