I think most people (myself included) do not understand how much technological improvement costs.
Anecdote: I once had a conversation with a guy who worked at ITER, and he was pretty bullish (and he had no reason to bullshit me) on the prospect of fusion as a viable energy source, but frustrated with the internal politics of ITER. So I asked, "well, what would it take? If I could call up a bunch of rich people to get funding, how much would it take?" He casually said, "oh, probably 1.2 to 1.5 trillion dollars". And then I understood why it was a multinational conglomerate that was funding it, and not a bunch of rich people.
