If you’re ONLY considering products then why even bother reading about research? Apples to oranges comparison.
There is research and then there’s vaporware which is design to suck in investment dollars and grant money with no chance of ever producing a viable product.

And the government is always ready to throw money at things that makes no sense - like electric cars.
