For those saying let's just build space-based telescopes, sure, but it's 10-100X more expensive For now. and even modest ground-based facilities produce 100GB

For those saying let's just build space-based telescopes, sure, but it's 10-100X more expensive For now. and even modest ground-based facilities produce 100GB/night these days, and you can't do that from space (yet). Yet. I think it's inevitable that astronomy is going to be space based well within the next 50 years.
