If it is possible to make small amounts of those elements on purpose as a byproduct, it can help to offset the costs of the reactor in some small way and help with isotopic/nuclear research in general. But that can be done in pretty much any fusion reactor design to some degree.
As for Alchemy of the future, If in a thousand years we can just built whatever materials we need (including potential ultra heavy stable elements) from raw subatomic particles we don’t even need mining, just gather up some hydrogen/helium from space and transmute it into whatever you need. food, fuel, structures, etc.
I stopped using Hotmail when gmail launched and I was given one of the early invites from a tech relative. I have the welcome email from '04.
But now I’m looking at moving my emails to a self hosted solution because they have used everything in my >20year email history for Ai and I don’t want that to continue into the future.
