The US National Ignition Facility has achieved even higher energy yields since breaking even for the first time in 2022, but a practical fusion reactor is still a long way off
You seem to be implying that fusion is a gimmick of an idea by comparing it to Hyperloop which was nothing but that.

This isn't even necessarily about a single company promising that they have an idea that may work, this is an example of it functioning in some capacity.
