Maybe cold storage of huge amounts of data in geosynchronous orbit could be a not-terrible idea. But I guess they'll want to keep latencies low and place them in LEO

Edit: Curiously, the last time I read this article several years ago it presented the consequence of making space completely inaccessible in the introduction (can't remember if sourced or not), while now halfway though the article, under "Implications", it says

The catastrophic scenarios predict an increase in the number of collisions per year, as opposed to a physically impassable barrier to space exploration that occurs in higher orbits. ^[citation needed]

I wonder if "in 2025 the number [of tracked space debris] was estimated at over 11,800, most of which (7,135) belonged to Starlink" has anything to do with that 😒
