People are motivated to replace it with something better, it's called Matrix 2.0.

Which perfectly fits the Matrix ethos of everything constantly being rewritten or replaced with something new that only implements half the features before the original thing is ever finished.

Do they plan to fix the fundamental issues of Matrix in 2.0 or should I wait for 3.0?

I tried it a year ago when it was introduced, it did not work. Is it stable now?
