I’m sympathetic to both sides here.

Obviously we cannot indefinitely build larger accelerators, and if it turns out that there is no support to go at least one size bigger, then perhaps our best hope is to find more effective ways to use the existing ones we have.

As a random example to illustrate what I mean: https://www.google.nl/amp/s/phys.org/news/2018-07-plasma-siz...

Maybe stopping here will force more thinking along these lines? I hope so, anyway.
