I'm glad you looked that up. More people need to know about Whitney. I wish he would open-source his work so we could learn from it.

But why do you say they are working in well-defined problem spaces? No more well-defined than most, I would have thought. Certainly Moore was a pioneer of iterative development and evolving a program (and notation) in the direction of the problem. That's why he invented Forth in the first place.

Edit: Oh, having looked up the Medawar reference I realize you probably mean "well-defined problem space" in the way a mathematician would: a problem space narrow enough to be effectively studied but rich enough to produce meaningful results. Certainly most software projects do not start out in such a space. On the other hand, we don't try to learn enough about our problems to find such spaces. We merely add code. One might almost say we excrete it.

Sorry, yes, I'm not a coder. Whitney is dealing with financial data sets of impressively huge sizes but he (to my limited knowledge) clearly understands the structure of the data and a range of queries at a deep level. Moore looks as if he his devising the hardware to run the code!
