Experiments have already reached the stage of producing more energy than required to start and sustain it. The only challenge left is to make it stable enough to generate power for a prolonged period.

And development of this tech is likely to develop sooner than you think thanks to AI and quantum computing. AI data servers will require enormous amounts of energy and they will also help accelerate research into fusion.

As for fission nuclear power, that has serious drawbacks, not least the fact that we really wouldn’t want a lot of countries to acquire fissile materials for obvious reasons.

There is no fuel for a fusion reactor.

The only challenge left is to make it stable enough to generate power for a prolonged period.

Because too much energy is required to inject into too small of a space. Here on earth, we don't have the gravity of the sun or 10 Jupiters to do the free work for us.

For fusion to work on a small scale, we need to alter the relative strengths of the electromagnetic, strong, weak, and gravitational forces.

But don't worry about that, fusion projects will always be well-funded, and the "breakthroughs" will continue for decades to come.
