@mpweiher I feel like your conclusion comes from a misunderstanding about what JITs are useful for /cc @asynchronaut @krono @smarr

@mpweiher there are domains for scripting langs where predictability is not needed, but speed boost are nice/cc @asynchronaut @krono @smarr

@mpweiher if your point was that an ObjC JIT is not required, I concur @asynchronaut @krono @smarr

@mpweiher but I know people that use pypy/jruby/rbx, and are simply happy when a small script finishes faster @asynchronaut @krono @smarr

@timfelgentreff Sure. But what's the penetration of Pypy, Jruby, rbi? Much smaller than I would have predicted. @asynchronaut @krono @smarr

@mpweiher @timfelgentreff @asynchronaut @krono @smarr what about V8?

@rguillebert Well, JS in general. Probably the most significant holdout, due to platform limitations. But note the apparent retreat from JS

@mpweiher @krono @timfelgentreff to use your words: you are on crack... At least for dynamic languages, AOT compilation is not cutting it.

@smarr I get what you're saying, but don't see where it actually contradicts what I wrote… @krono @timfelgentreff

@mpweiher you're saying that JIT compilers are phased out, which I don't see happening. For Hotspot, AOT is supplementing JIT compilation,

@smarr I don't think (or wrote) that they will be phased out completely soon. Too much inertia. Their importance is diminishing greatly...

@smarr and they are fading away...slowly

@mpweiher I don't think so and I see no indications for it happening. People work on fixing startup performance. But that's a good thing.

@mpweiher JIT was always poor for the user; it traded the user’s for developer convenience. A trade that should not be made, in my opinion.
