I don’t think fusion would be as useful a technology as it would have been a few decades ago. Now renewables (wind, solar, hydro) seem like more and more as the clean and cheap energy of the future. The biggest problem of storage is rapidly being solved with batteries springing up everywhere.
The real problem with fusion is that even if it worked, the plants would be very complex and expensive. It would be much cheaper and reliable to build solar, wind and batteries instead.
Having operational fusion reactors would be cool as hell, but it wouldn’t have that much impact on our lives in the end.
Respectfully, I disagree. We’ve entered an AI boom, and right now, the star of the show is in a bit of a gangly awkward teenage phase. But already, these large data models are eating up mountains of energy. We’ll certainly make the technology more energy efficient, but we’re also going to rely on it more and more as it gets better. Any efficiency gains will be eaten up by AI models many times more complex and numerous than what we have now.
As climate change warms the globe, we’re all going to be running our air conditioning more, and nowhere will that be more true than the server centers where we centralize AI. To combat climate change, we may figure out ways of stripping carbon from the air and this will require energy too.
Solar is good. It’s meeting much of our need. Wind and hydroelectric fill gaps when solar isn’t enough. We have some battery infrastructure for night time and we’ll get better at that too. But there will come a point where we reach saturation of available land space.
If we can supplement our energy supply with a technology that requires a relatively small footprint (when it comes to powering a Metropolitan area), can theoretically produce a ton of power, requires resources that are plentiful on Earth like deuterium, and doesn’t produce a toxic byproduct, I think we should do everything in our power to make this technology feasible. But I can certainly agree that we should try to get our needs completely met with other renewables in the meantime.
While I agree with what you’ve said, I’ve always felt fusion and other such tech is the future of long distance space travel, not Earth based energy use. Wind and hydro are useless in space and solar has issues with power accumulation the further away from a star you go. We will still need some kind of “fuel” based energy source if we’re ever to enter deep space and cross the gaps(unless battery tech increases much further to the point that a “battery” lasts a significant portion of the vehicles lifetime). Even then, you’d need recharge stations at each end or to park by a star to refuel in between.
We have fusion/fission now. That kind of battery tech is still a ways off. Feels shortsighted to ignore nuclear now just because it’s not perfect in this specific environment.
Fusion is likely the end-game power gen tech for humanity, assuming no new physics (and excluding Dyson structures). For the long term, it likely will be the most useful way of generating mass amounts of electricity you can get, and access to more energy enables more possibilities of all sorts of things, enabling even things that are extremely impractical today due to their energy needs
For example, carbon capture becomes a possibility, and stuff like mass desalination. And then you could, in theory, go even more extreme with stuff like terraforming mars at human timescales, with enough energy. Of course this depends how practical and efficient fusion reactors actually would be, but with enough energy you can do so so much

If we have a lot of cheap energy, we might be able to do industrial-scale carbon capture.
