How so? I've always felt that intuitionism/constructivism were closer to theoretical computer science due to constructivism requiring you to produce (or compute) the what you're trying to prove.
The state space is far too large to show a program is correct by constructing all possible processes it could execute. Instead you must show that the program admits no incorrect processes whatsoever, and as far as I know mathematical formalism is the only possible way to do that.
Of course if one just wants to make money, formal correctness is observably of absolutely no importance. And there's nothing wrong with wanting to make money!
