Simple answer, yes. Not saying that Ruby is fast now, however Ruby doesn't necessarily always have to be slow. Just like any languages/framework/etc. It can be made faster, although the amount of work to get there may be substantial.

At the time ruby was really slow, and with no real progress and a waning number of groups working to improve it. Now, it appears people are making progress and working on it.

This is correct, I would highly highly recommend reading "Deoptimizing Ruby" available here, http://chrisseaton.com/rubytruffle/deoptimizing/ for more information on WHY making Ruby fast is hard and what the Truffle+Graal does to make it fast.

That's a great read even if you aren't a Rubyist, especially the discussion of monkey patching.
