I don't think a really big computer would have to collapse into a black hole, if that is what you are saying. You could build an active support system into a large computer. For example, you could build it as a large sphere with circular tunnels running around inside it, with projectiles continually moving around inside the tunnels, kept away from the tunnel walls by a magnetic system, and moving much faster than orbital velocity. These projectiles would exert an outward force against the tunnel walls, through the magnetic system holding them in their trajectories around the tunnels, opposing gravitational collapse. You could then build it as large as you like - provided you are prepared to give up some small space to the active support system and are safe from power cuts.
What is the problem with whoever voted that down? There isn't any violation of laws of nature involved in actively supporting something against collapse like that - any more than there is with the idea that inertia keeps an orbiting object up off the ground. While it would seem to be difficult, you can assume extreme engineering ability on the part of anyone building a hyper-large structure like that in the first place. Maybe I could have an explanation of what the issue is with it? Did I misunderstand the reference to computers collapsing into black holes, for example?
hyper-large structures are hyper-slow and hyper-dumb. See my above reply. The future of computation is to shrink forever. I didn't downvote your comment btw.
