Very vaguely related to image detail but you know what similarly impressed the heck out of me:

you know that first ever imaging of a black hole using telescopes across the globe and even the poles to make the signal gathering as wide as possible?

well that telescope (interferometer) could also image a TENNIS BALL on the MOON

(in perspective currently 5 meters is the best resolution of the moon we have and they only get like one or two photons back when they bounce a laser off that mirror the astronauts left there)

So are we going to enter an era where we can get ten more times out of existing telescopes with exponentially better sensors?

There is fairly significant difference in radio observations and visible spectrum imaging though. You aren't going to get 5m resolution visible light image of the Moon any time soon.
