No it won't. There are so many problems with trying to get a dynamic language like ruby to be in the same order of magnitude of performance as C.

Garbage collection, inlining virtual calls etc.

[melling]

Go has garbage collection and it's in the same order of magnitude as C. In fact so are Scala and Java. So, we can at least stop blaming gc.

[andrewvc]

Yes, but neither language is nearly as dynamic as ruby. That's where the costs come in. Method calls in ruby are comparatively glacial in speed.

That's why the ten years.

[lispm]

after ten years, square wheels will suddenly be round?

[haar]

If you've been rotating them against a surface in that time period; then they'll certainly be a lot more round than when they started.
