With the amount of 3x3 world record singles that have been broken in the last 3-4 years, it has me thinking about the possibility of a world record solve that is unbeatable, and or impossible to surpass. I feel the 3.47 single shook the cubing world, and many didn’t expect it to be possible, especially from a small cuber in China that had an in-competition average of 7-seconds, plus I think I can speak for the whole cubing community when I say that the fact it wasn’t Max or Feliks was pretty shocking as well. So with all this in mind, we have to stop and think, will the 3x3 single get to a point where it is literally impossible to beat, and will remain unbeaten for the entirety of the cubing world to go on. Now I can see someone getting 3 seconds and possibly sub-3 seconds. However, if that were to happen I feel it would not be possible to be beaten again, considering how lucky and rare a scramble would have to be for it to happen, also you have to include the fact anyone could get, “said” scramble in comp, and it could be someone who averages 30 seconds who would screw it up or it could be someone who averages 5-7 seconds and could actually achieve such a feat. So with all this concluded, in my personal opinion I feel sub-3 single is 100% possible, and I believe you could say anything past is impossible for a human to do, because you would have to have cross and f2l practically done and have to get an OLL skip.
