Nuclear Fusion Breakthrough....What Does This Mean?

Click For Summary
The recent confirmation of a nuclear fusion breakthrough by a California team, achieving ignition, is viewed as a significant milestone in fusion research. However, some experts argue that this achievement is incremental and may not lead to practical, affordable fusion energy in the near future. Critics emphasize that the National Ignition Facility's primary focus is nuclear weapons research rather than developing commercial fusion energy. Additionally, concerns have been raised about the facility's ability to replicate the ignition results consistently. Overall, while the breakthrough is noteworthy, its implications for energy transformation remain uncertain.

It is an incremental improvement past an arbitrary "milestone". Don't count your neutrons before they hatch.

I would not chacterize ignition as an arbitrary milestone. One the other hand, I am not selling my oil stocks.

Nuclear Fusion Breakthrough Confirmed: California Team Achieved Ignition​

For those of us not literate in the field, how significant is this and what are the prospects for a true energy transformation from here?
Of course the National Ignition Facility is going to claim achieving ignition is a big success since it's in the name but the reality is a sport-stadium size laser is not going to bring about an era of cheap fusion. The main purpose of the NIF is nuclear weapons research, not practical fusion.

Also, it seems NIF has not been able to repeat the experiment of August 2021 so has resorted to 'confirming' the earlier result.

What type of energy is actually stored inside an atom? When an atom is split—such as in a nuclear explosion—it releases enormous energy, much of it in the form of gamma-ray electromagnetic radiation. Given this, is it correct to say that the energy stored in the atom is fundamentally electromagnetic (EM) energy? If not, how should we properly understand the nature of the energy that binds the nucleus and is released during fission?
