Is it really a 'scientific breakthrough' if it's just that they've firing fusion shots with 'net positive energy output'?

Good work, but IMHO we're still a long way from using fusion for energy, if ever, even if only because it will be so expensive to build and run these ultra-high-tech plants. But also because of all the downsides of D-T fusion, like, where is the tritium, and that most of the energy comes of as fast neutrons, etc.
