Curious about this (https://en.wikipedia.org/wiki/Particle_accelerator)
Log-scale plot of constituent center-of-mass energy in GeV against year of first physics, 1960 to 2020s, showing hadron colliders rising steeply and e+e- colliders plotted lower, with labelled machines such as ISR, Tevatron, LEP II, LHC and LC.

which indicates diminishing returns on new particle accelerators. However to uncover new physics, presumably you need to keep increasing the Lorentz factor by the roughly 10x trend here:

Scatter plot titled Lorentz Factor, particle accelerators, lab frame: log-scale Lorentz factor against year from 1930 to 1997, rising from about 1 to about 10^7 in red open squares.

So is this hopeless?

Feynman writes about this in the Character of Physical Law. He did forecast that it likely will become increasingly difficult to get fundamental scientific discoveries.

I think this doesn't just apply to particle accelerators but to pretty much everything. Like mining ore for example, the easily accessible one gets mined first and fastest, then as you go deeper for more the ore gets less and you get more investment for less return.

Those graphs seem oddly similar to Moore's law for example, and we know now we are at the point where the climb in the graph is going flat.

These are both cases of Stein's Law. "Things that can't go on forever won't."

One interesting comment in the Powers of Ten video...

on the return trip
(?t=5m10s) "Notice the alternation between great activity and relative inactivity, a rhythm that will continue..."

 
Although to note one thing, unlike the feature size on microprocessor architecture where we know there won't be any surprises and a minimum is/will soon be reached in high energy physics we don't know whether or not something interesting might still be hiding at a higher energy that we have not yet accessed.

So in a sense it's not a straight forward comparison
 
Also there is a positive feedback with moores law - smaller microprocessors are more efficient (per transistor) than larger ones - the power usage of processors has remained about flat for the last 20 years - with particle accelerators inefficiencies would increase with size

  • Log-scale plot from about 1972 to 2015 with five trend series: transistors (thousands), single-thread performance (SpecINT), frequency (MHz), typical power (Watts), and number of cores, each rising then flattening after about 2005.

Well, to uncover new physics one may need something else apart from higher energy, for example, detector/technical development in some other part of the experimental setup.
