Edit: Also, a telltale question: do you think he ever actually built anything with Lisp or Scheme? I'll bet he went straight to "improving" on it.
Edit 2: moved irrelevant bit to a different comment.
I know this sounds cranky. It's because I started my professional programming life in this dark forest and it took years to find my way out. And I think it's a shame that they dominated the industry for as long as they did, because they wrought such damage on the level of ideas.
There's a certain type of smart-but-ignorant programmer who is infatuated with his own IQ, doesn't want to learn from anybody who knows more, and just cranks out reams of code (often filled with pseudo-abstractions that make it a lot worse than plain old bad code). I think of MS as the corporate equivalent of this type.
Edit: I should add that not everybody at MS is like this, of course. But the exceptions are people who grew up outside that culture.
Despite the numerous critique I partially agree with, Microsoft showed the continuous commitment to improve their software, and I personally still think that staying with them, as a profesional developer, is not a bad choice.
No, our industry is slow on the uptake.
Microsoft makes products. They don't make languages to be cool or expressive or powerful, but as products to sell.
