Nowadays, people worry about a “desert scenario,” where no new particles will be found for many decades to come, if ever.

This point of view is wrong.

The first two decades of this century have been pretty successful for physics:

1. the discovery of the Higgs particle
2. ...

Busy should not be a badge of honor.

If directed at the wrong pursuits, it is actually a limiting factor to our full potential.
