They mention his tariffs, but it's also a bigger issue that has to do with the laws of physics hitting economics.

We've been up against the 5Ghz thermal wall for over a decade. We can keep adding cores but we need significantly improved design (less nanometers) for these gains - and these are now running up against another wall, namely quantum tunneling which begins being a problem at around the nanometer scale.

I assume only a radically different architecture (light instead of electricity?) will be able to smash these barriers.
