Good overview but a bit more hopeful than I would be. My bet is closer to 50 years if ever. But we must try if only for the side effects of the R&D (e.g., space travel).

Here is a deeper dive on the difficulty of the practical fusion energy problem. It is very easy to understand and it is much worse than you and the other media are letting on:

The hohlraum is just a highly engineered cavity needed to contain the frozen hydrogen pellet and give access to the lasers and it looks like this:

All the fusion designs depend on cavities. The big alternative, a torus, is just a toroidal cavity where the hope is never to need a hohlraum that gets destroyed immediately by the fusion itself. In the toroidal designs the fusion reaction is contained electromagnetically safely away from the inner walls of the torus. Neither technology is at all proven for even a hint of practicality still. We need to keep the lies in check. The truth is good enough to keep up the work.
