Why fusion, over everything else?

$15.2 billion in private investment over the past 5 years!

For an industry that is projected to need 1 million workers by 2040, how is the global private workforce roughly ONLY 4,000?!

Fusion makes big promises but is still pretty speculative. If it works the way people claim, it could provide cheap and clean electricity without the same resource constraints as fossil/nuclear.

The way I heard a VC guy say it recently was that right now, the market is pricing in 2% odds that fusion will meaningfully contribute to energy within the next couple decades. If that 2% hits, the people investing now in the right companies make insane amounts of money, and even if the market just shifts to there being a 4% chance then they can get their money back.

In terms of workforce, it's not like every job in fusion will be a PhD who needs 10 years of training. Most jobs will be the same as in other industries (purchasing, HR, etc.) or be adjacent enough that skills are transferable (management, electronics/controls, materials, nuclear engineering). Right now there aren't that many companies, and they're not paying that much more to get people to switch from other industries. Maybe if successful designs actually materialize then that will change

As someone actually working at one of these companies, the compensation narrative doesn't match what I'm seeing on the ground. That's not the bottleneck....not even close.

The harder problem is that there's no established talent pipeline I would guess?
Fusion sits at this weird intersection of plasma physics, cryogenics, high-power electrical systems, and mechanical engineering that doesn't map cleanly onto any single degree program. You're not just hiring an engineer...you're looking for someone whose background happens to overlap several very specific disciplines, and that person is rare regardless of what you're willing to pay them.
