Chemo is so toxic that the people administering it cannot even touch it.... and don't get me started on radiation.

These treatments are brutal, carcinogenic in their own rights, and are not even necessarily curative. Crispr enzymes coded specifically to attack cancer DNA has been proven to not affect ANY healthy cells, while selectively annihilating cancer cells in vivo.

ya you break down mercury for components. Or use stellar lifting to directly pull iron and other elements from solar plasma .. This is all a 100% do able.. it just a multi + generational project with current technologies. And it get a lot easier with functional fusion and AI systems

Its also a natural progression of something we are going to want to do anyway.

Many chemotherapy drugs are designed to inhibit or kill rapidly dividing cells which allow us to hit cancers with some specificity but other cell populations are also hit as a side effect. This is the reason why many people on chemo lose their hair; hair follicle cells are susceptible to the same chemo drugs.

Radiation is targeted by aiming a beam at the tumor. By using multiple beams that converge at the tumor site, we can ensure that surrounding tissue receives a lower more tolerable dose.

It is not, no. Perhaps the individual components are, but to Dyson scale, you'd need more literal material than the earth.

So you'd need to have a feasible way to mine, refine and manufacture in space, at scale. That does not exist. You'd also need advances in spaceship technology for all the mining and hauling materials and machines for processing.

In fact, I think even swarm, you'd need more material than all the rocky bodies in the solar system combined, so on top of being able to just strip all bodies including earth to nothing, which is not feasible with mining tech, you'd need interstellar travel to other worlds, and perhaps a way to harvest stuff off gas planets, etc...

So, the tech does not exist. Just ability to build small parts of it.

Next up, is building a dyson sphere even worth it, considering what other options open up once you have technology for that level of space travel, and resource harvesting needed for production at that scale?

Likely not.

>AI can't distinguish these things.

I'm not sure how true that is though. Even with GPT3, it would actually take into account the context of the whole conversation instead of just the most recent sentence when I asked something.

Hard to say how well it would handle itself in a real-world environment though since it's just a chat-bot atm.

It quite feasible... you could literally do it with zero advancement in current manufacturing technologies it just be pretty slow. (way faster if you had space base industry first though.. or a lunar manufacturing colony)

A dyson sphere.. as outlined by Freeman Dyson propose a swam structure. For example the simplest and easiest dyson swam would a collection Mirror arrays that would let you directly control solar output for energy collection.

So think structures like countless medium size satellites with football field size Mylar reflectors in orbit around the sun. You need to get the orbital mechanics right to account for radiation pressure from Sol.. but super do able .. and Even well before you hit Dyson swarm like size.. something like this would be super useful for power collection is you had some optics to focus the energy

>If the AI can not recognize an obvious drive-through it would be the AIs fault, but why do you suppose that is the case?

i already told you because "drive through" is an abstraction or a concept, it isnt any one thing. anything can be a drive through. And AI can't comprehend abstractions. sometimes the only clue you have to perceive a drive through is a line. not all lines are drive throughs, and not all drive throughs have a line. they are both abstractions, and there is no way to "teach" an abstraction. We don't know how we know these things. we just do.

another example would be "farm" a farm can be anything. it can be in your backyard, or even on your window sill, inside of a building, or the thing you put ants in. so to ask and AI to identify a "farm" wouldnt be possible.
