Don't get me wrong, QM for example was ridiculously useful. But, pointing to past and saying these tiny particle accelerators where useful let's make a multi billion dollar one feels like cargo cult science for the lack of a better phrase. We just keep piling higher and deeper without a clear reason to do so other than we can afford to do so.
String theory is another example where lot's of effort from seemingly smart people with no practical basis.
Dumping all of LHC's money into say a large ITER style fusion project would have also been cutting edge, but there would have at least had the possibility of useful results. Hell, even ISS would qualify as vaguely useful.
How about a self sustaining bio-dome in Antarctica. Now that's probably harder and possibly more expensive, but would have real useful applications if we ever want to try and colonize Mars.
PS: Not that the 13+Billion for the LHC was all that expensive, but there are a lot of similar projects out there.
GH Hardy famously predicted that elementary number theory would have no practical applications. Lo and behold, today it is an indispensable part of web cryptography used by hundreds of millions every day. Waiting on the order of decades for a ROI on fundamental research is simply part of the game. I suspect the point where we experience diminishing returns from this is much to far in the future to even consider the question.
Elementary number theory is the opposite of what I am talking about. RSA is from the kiddie pool of that field.
Consider, we know the first five digits of the gravitational constant. So, while it might seem like the diminishing returns are a long way off. Yet, each extra digit becomes exponentially more expensive and less useful. So, actually learning g out just 9 digits is probably a huge waste of resources.
Or in the words of a physicist, in 1920 second rate physicists where doing first rate research. Now, first rate physicistare doing second rate research.

In number theory, what's considered 'elementary' now was cutting edge in the times of Diophantus, all the way to Fermat, to Euler, to Gauss (etc). The fact that children are now routinely conversant in it, I think, is another point in favor of the importance of making such discoveries in the first place.
My point is that applications that were never envisioned for these (at the time) centuries-old-facts, are now commonplace and indispensable.
I think that there is a bit of survivorship bias that warps our understanding of old science. We remember only the great discoveries because those are the most likely to be republished and read.
Also, in the case of math, it is my impression that an amazing amount of very significant progress is being made in the present era.
It was old hat 1500 years ago, and rediscovered repeatedly. I am suggesting there is a legitimate separation from what people find out in the first few years of research on a topic and what's built after that. So, you really need to pick a deeper topic if you want to defend your argument.
As to survivorship bias, that's huge but it's not just based on good ideas. Copernicus was ~4,500 years late to proposing the sun was the center of the solar system. But, the pop story looks better when Darwin is breaking new ground instead of simply collecting more evidence in support of an old theory.
As to Amazing progress, I would hope the ~1,000,000 active mathematicians are not all wasting their time. But again, the point is we don't need to maximizing the number of Mathematicians, we are well into diminishing returns.
