You seem to have misunderstood the comment, (the sibling comments should help explain, or maybe some light reading about the invention of the transistor).
What I am guessing went wrong here is that you are unfamiliar with sarcasm, so I'll help you out: I don't actually credit Feudalism with the invention of the transistor.
I'm not even going to go into how a lot of that spending, if freed up, would go toward endeavors that are not military related and to a parallel timeline we can never know. Imagine NASA with 10 or 50x the budget. Or NSF with 10x the budget, etc. We'd probably be typing this on a moonbase or on a cottage on Alpha Centauri's earth-like planet.
Instead we fawn over the peanuts that falls out of the elephants mouth and praise its generosity for feeding the hungry.
Transistors discovered by a private lab? A private lab with government funding? A private lab building on work done by individuals such as Faraday? Individuals who in many cases received government funding in the UK? Individuals who were building on work by Benjamin Franklin, a self-made and self-funded man? Benjamin Franklin, who doubtlessly was enabled by early work on the scientific method itself by Roger Bacon? Roger Bacon, who was supported by the catholic church? Roger Bacon, who built on work of earlier Muslim scholars?
If we want to play the "who gets credit" game, we need to decide beforehand how many times we are going to go down the "who funded who" tree, and "who researched the prerequisites" tree.
I'm not talking about politics; I am pointing out that you people are talking past each other because you all have different ideas of how to assign credit.
