Well, the typical way of measuring q does measure the energy it takes to get the boulder up the hill, but not the inefficiency of the machine to get the boulder up there and the ineffency in extracting its energy as it goes back down.

There’s a lot of unsexy research that could make fusion come a whole lot sooner. More efficient powerful lasers, better cooling methods and design for superconducting electromagnetics, more efficient containment methods and more thought on how to extract energy from the plasma efficiently, and then making it cheap enough to build and maintain that we can actually afford to build them.

You’re right, copyright won’t fix it, copyright will just enable large companies to activate more of their work extract more from the creative space.

But who will benefit the most from AI? The artists seem to be getting screwed right now, and I’m pretty sure that Hasbro and Disney will love to cut costs and lay off artists as soon as this blows over.

Technology is capital, and in a capitalist system, that goes to benefit the holders of that capital. No matter how you cut it, laborers including artists are the ones who will get screwed.

Hopefully, it can also be used to prove that someone was not at the scene of a crime, enabling prosecutors to rule out suspects and innocent people to get off.

The person outright rejects defederation as a solution when it IS the solution

It’s the solution in the sense that it removes it from view of users of the mainstream instances. It is not a solution to the overall problem of CSAM and the child abuse that creates such material. There is an argument to be made that is the only responsibility of instance admins, and that past that is the responsibility of law enforcement. This is sensible, but it invites law enforcement to start overtly trawling the Fediverse for offending content, and create an uncomfortable situation for admins and users, as they will go after admins who simply do not have the tools to effectively monitor for CSAM.

Defederation also obviously does not prevent users of the instance from posting CSAM. Admins even unknowingly having CSAM on their instance can easily lead to the admins being prosecuted and the instance taken down. Section 230 does not apply to material illegal on a federal level, and SESTA requires removal of material that violates even state level sex trafficking laws.
