I agree with you, though I'd like to note that he's just the creator of 'Ruby on Rails'...

I would trust the real creator of Ruby, Yukihiro Matsumoto, a lot more than that Hansson. I looked at Ruby before all this Rails business, and it seemed pretty good for some tasks, but I never used it for something usefull (I learned Perl afterwards for work, and it seems to fit better for what I do).
