I mean, I'm most impressed with the gradual rise of 3d printers capable of printing entire houses.

That doesn't help with plumbing, electrical, kitchen cabinets and all the other stuff that goes into a house -- which is a majority of the cost -- but it's a gradual start.

I see very little which can't be automated, but I see a lot which would take many years of time and effort to automate and integrate.

They've got death robots that can fly now.

Why is nobody impressed by the future?

I believe those are human controlled, no? Robotics gets really interesting when the robots can start driving and building the roads as well.

Not necessarily. Some just require human to turn it on and it'll loiter and attack enemy autonomously (loitering munition [1]).
