The problem at hand is not just getting rid of heat however, it's getting rid of heat without cooking the Earth. I still fail to see how generating the heat off planet fails to solve that.
Snap judgements are human and inevitable, but acting on them isn't.
I'm agreeing with you!
> Using an entire Mars only nets us about a 2x multiplier for our energy expenditure budget.
We don't need to care about cooking Mars.
When we're talking about creating powerplants equal to roughly 5% of the insolation of Earth, I think we're sci-fi enough to discuss orbital datacenters or Mars datacenters or Jupiter fusion candle datacenters.
If you replace "LLM" with "mathematician" than this is the state of the world today. Stuff like Galois theory is beautiful mathematically, but what has it constructed or enabled for you and me?
Stuff! Inscrutable stuff, maybe, but that's not "doing math for math's sake."
First principles: "We need X, how can we accomplish that?"
Higher order: "We need X, what would accomplishing that do for us?"
Damnit, I rewrote that sentence twice and still got it wrong.
Why not?
> That’s just me as a private entity snitching.
... to the state. You are surveilling for the state.
Domestic surveillance took off with McCarthyism.
Higher order: What if we accomplished X?
And who should first principles focused on? Your customer, your manager, your company, yourself? All of these are valid and often give competing answers!
A spent solar panel contains the exact materials needed to make a new solar panel. Chemical changes are cheaply reversible, so you can turn an old solar panel into a new one for less energy than it will produce during it's lifetime. A solar panel factory can operate indefinitely. (Or at least for as long as their is solar energy available.)
Nuclear fuel must be mined. Nuclear changes are reversible, but that requires the same amount of energy you would get back out. The Earth has a finite amount of nuclear fuel. (To be fair, there's a lot. The Earth contains enough fuel to last roughly the lifespan of the Sun.)
This supports your point even more!
I would argue that has done more harm than good. Strong media personalities shouting "the next big breakthrough is here!" followed by 25 years of zero practical results have not done good things for public perception of field of physics. A layperson could be mistaken for assuming the field is literally regressing.
I (a human) am interested in things that are applicable to my realm of understanding, but I see a very plausible future where novel and/or valuable results leave that realm.
I'd further argue that's already the case for most math for most humans. What's interesting to Terrance Tao is rarely of immediate interesting to me.
