> We still don't have space stations that can accommodate more than a half dozen people. We don't have Moon colonies. We don't have 3D holograms (not the ones that rely on spinning a stick really fast and using a projector). We still don't have a cure for any type of cancer. No warp drives. No anti-grav. No 200 year life expectancy. No human cloning. No $25 000 flying cars. No mass produced technology or consumer products using graphene.

All of these statements apply to Einstein's era as well.

We do, however, as of the past ten years or so have reuseable rockets (non trivial), inexpensive virtual reality goggles, mRNA vaccines, bioreactor grown meat, on demand access to an enormous quantity of humanity's artistic creations at any time, nearly-out-of uncanny valley digital human replicas, self driving cars with a low probability of killing you getting from point A to point B, and, yes, some really cool video games.
