It reminds me of the early days of Biotech, and software, where some people did get very rich.
Some of them will lose heavily I predict, particularly those investing in fusion hype.
Many of the fission based investments will also be losers, but some will be big winners, like Oklo for instance and others.
In the last several weeks, two new nuclear reactor types went critical - at near zero power however - six others will probably do so in 2026 in the US alone.
We are entering a new nuclear Era, where the creativity in reactor designs is going wild, comparable to the First Nuclear Era covered by Alvin Weinberg in his book on the subject, which my son ripped off from me (albeit with my permission). A lot of what was learned in the first nuclear Era from the late 40's through the early 1960s is being dusted off and studied. This is a very good thing, too little, too late perhaps to have avoided the ongoing tragedy of fossil fuels, and maybe too little to late to slow the destruction, but we must do what is possible, including some of what we regard - until we learn better - as impossible.
