> it is possible to put 500 to 1000 TW/year of AI satellites into deep space, meaningfully ascend the Kardashev scale and harness a non-trivial percentage of the Sun’s power

We currently make around 1 TW of photovoltaic cells per year, globally. The proposal here is to launch that much to space every 9 hours, complete with attached computers, continuously, from the moon.

edit: Also, this would capture a very trivial percentage of the Sun's power. A few trillionths per year.

Only people who never interacted with data center reliability think it's doable to maintain servers with no human intervention.

Do they need to be maintained? If one compute node breaks, you just turn it off and don't worry about it. You just assume you'll have some amount of unrecoverable errors and build that into the cost/benefit analysis. As long as failures are in line with projections, it's baked in as a cost of doing business.

The idea itself may be sound, though that's unrelated to the question of whether Elon Musk can be relied on to be honest with investors about what their real failure projections and cost estimates are and whether it actually makes financial sense to do this now or in the near future.

AI clusters are heavily interconnected, the blast radius for single component failure is much larger than running single nodes -- you would fragment it beyond recovery to be able to use it meaningfully.

I can't get in detail about real numbers but it's not doable with current hardware by a large margin.

eh? They're not gonna lay cable in space. The laser links will be retargetable.

How are you doing pci express x16 with lasers without fiber optics? Have you touched data center hardware in your life?

Lasers, space, super geniuses, and most importantly money. You're worrying too much about the details and not enough about the awesomeness.

But seriously, why are all the stans in these comments as unknowledgeable as Elon himself? Is that just what is required to stan for this type of garbage?

What if every installed twitter app just acted as a proxy for grok to post as millions of different elon stans? Diabolical.
