So what exactly is the benefit of having that thing in orbit then, where it costs you millions of dollars to put it there?
Self destruction is a feature, not a bug.
That said eventually they can be lifted to higher orbits and have robots deliver and swap updated compute (if not made in space itself!).
The current bottleneck on compute is power and zoning. Solar panels are 5x more efficient in space, and there is no zoning in space.
