The car of the future fixes many of the problems, and it fits right into existing infrastructure. Think autonomous electric single/dual occupant taxis (2+ per lane).
We are still a ways off, but this is where things are headed.
We might not need the parking, but the roads will be useful.
I can't get past the fact that the software, in order to interact with the 3D world, will be expensive and cumbersome to make. Also, people (your income) born before AR tech generally don't want hardware on their face.
This, and Hololens, and similar, will fail for a while, and I'm thinking it will be decades. I'm placing my bet now.
I think the difference here is that the goal is more ambitious (100% diet replacement). Ensure is explicitly a dietary supplement. The marketing, cost, flavor, and nutrient profile reflect that.
It's like wanting to enter a high end auto race and you just buy a sports car off the lot. It will be expensive and slow. The fast cars are custom built because the market is small and the requirements are unique.
In exchange for clean, constant, domestically sourced, almost unlimited energy for an entire year, each person must dispose of or store their waste, which is the size of...
A pill of aspirin.
You could just put it in a little lead jar. That's all the waste. The alternative is fossil fuel waste, which would be...
10 tons of CO2 (volume = 5 American houses) which floats into the atmosphere, plus 2 tons of coal ash.
Of course, everyone can just pool their resources and put all the radioactive waste together. I don't consider it to be a very serious or unsolvable problem.
