I directionally agree with you. But there are plenty of examples of scientists being extremely petty, political or egotistical further back in history. Newton and Leibniz. Gauss withholding publication of non-Euclidean geometry presumably due to fear of Kant.

I wonder if there is any empirical analysis of what has historically funded/supported scientific work (private funding vs. academic systems).

I also wonder whether a lone genius in it for the "love of the game" could make much progress in cutting edge science nowadays, given the cost of experiments and the specialization of fields.

Really interesting food for thought.
