I just upgraded an app we've been developing in 3.0.0.rc2 and it went smoothly. Looking forward to actually having the docs in place. It's really been a lot of fun implementing the new changes and I'm excited for everything - hopefully the performance issues will get there, though, I've heard (though not personally observed) that the ActiveRecord in rails3 is something like 50% as fast as 2.3.5 was...

That quote is simply stunning. Clearly, us as a people and civilization is retarded if we are so dumb as to let "science" be the limiting step in progress and not just the imaginations of our sci-fi writers.

Not that much of the rest of the post isn't worth considering, but that statement surely needed comment. Clearly we're not even CLOSE to figuring out how to do all those things.
