We already have computers wildly more advanced than anything in Asimov's universe (until his very late writings), even as his robots firmly remain science fiction.
Yes, we know that he was wildly wrong about what would be easy and hard about robots and computers. It is bizarre to go back and read his stories in which robots are walking and talking, but it takes a massive robot brain installed in a permanent emplacement to get little more "raw" computational power than a 1970s mainframe. Unless you travel back in time and reveal the secrets of robotic brains to those in the 1950s, it's a done deal.
