Yes, some people wondered if PyPy is "the future of Python" - but it didn't take over the Python ecosystem. If the initiatives mentioned in the article will yield a 100%-CPython-compatible implementation that is always faster and doesn't have big warmup slowdown, it could be "future of Python".

I've been testing it Gtk stuff each release for a while now, it seems really close to working with the things I need (CPython libs). About 3 years ago, I couldn't have guessed it would come that far + this is as a fan/lurker of their mailing list :)

I'm also surprised that it mostly works with extensions written for CPython. Unfortunately there's a big difference between working in 99.9% of cases vs 100%...

Actual target is not 100%, but CPython interversion agreement, because CPython versions (say 3.4 and 3.5) are not 100% compatible with each other. I think PyPy can reach that target some day.
