- Active camouflage, Predator style.

- something close to the Holodeck from Star Trek. But I feel like it won't take long anymore with VR and AI

- more space missions. For many large bodies in the solar system we still don't know how they look.

- Moon colony, Mars base, Venus explorative missions (with Zeppelins!)

- Space station(s) with rotational gravity - 2001ish at least, or perhaps even Babylon5 ish

- floating (on water) cities, or under the oceans, like Jaques Cousteau believed in

- massive solar farms in deserts, massive wind farms in the oceans. Instead we trickle those here and there in areas with much less sun or wind. Like my own country Germany which is one of the least sunny places in the world, yet one with the most solar energy.

None of these things are actually useful, except camouflage. It's entirely pointless and wasteful to make space missions. The Apollo program was a waste of money.

I would say the active camouflage would be the least useful thing among this list. Developing space technologies on such a scale is sure to give a return on terrestial life, creating living space on or beneath the ocean has obvious advantages, as have solar and wind power clusters in appropiate locations.

Perhaps the holodeck thing is actually the least useful, but even that is creating massive technological progress from the sub-technologies required to get there.

Talk to most people here and they say sending anyone to make a moon base is a waste of money, and Mars would never be terraformed no matter how much time passes.
