"speed" thrown without context is meaningless. It's one property of a tool among many others you generally have to trade for.

Some use cases with small margins call for the utmost efficiency to be viable business. Some use cases just need decent efficiency and are happy to trade some efficiency for some other properties.

Many successful people and companies are happy with Ruby, can we just give them a break? Or is there somehow some moral duty to use the "fastest" language available regardless of whether it makes any kind of business sense that nobody told me about?
