> For less starving people? For less child abuse? For less climate change?

Yes. The only way to truly solve these issues is technological progress.

Not really, all three of them are sociological problems. And, at least for the first and last, we could already have mostly solved them but for the intransigent insanity of various political cults.

It's not technological progress we need; it's cultural progress.

Logistics of food distribution is a technological problem, and nowadays famines tend to happen less due to absolute shortage of food in a wider region, rather than due to insufficiently developed traffic infrastructure.

IIRC no place in the world which has hard-paved highways has ever seen a peacetime famine. That's almost exclusively the domain of mud road territories. Of course, this is partly a correlation (mud road territories have worse governance and more banditry), but there is causality as well.

Well the only thing that has ever solved starvation is improved technology, child abuse I think has nothing to do with satellites, and managing climate change requires massive energy and technology resources especially in space.

So clearly you are in favor of starvation and human suffering due to climate change because of your irrational distaste for seeing satellites in orbit.

I suspect the root cause is you've overdosed on propaganda on the internet.

How is Elon Musk going to poison our atmosphere?

The Starlink satellites burn up in the atmosphere as they end their useful life. The metals that the satellites are made up of don't vanish in the thin air up there. They burn and just hang up there. Now, whether or not this is an impending disaster is for you to decide, but that's the theory of it.
