It’s is on earth as well using solar and batteries. What is likely to get cheaper faster? Solar and batteries? Or lifting datacenters to space? The world is almost at the point of deploying 1TW/year of solar, and batteries are catching up. No space required. There aren't a lot of VC investment opportunities speeding the rate of solar and battery deployments though.
The argument probably is that battery advances require not yet existing tech via new chemistry etc while what they are proposing is basically just integrating tech that already exists
But this is not the case, as it relates to the battery manufacturing pipeline and capacity. Battery supply exceeds battery demand.
