|Is there anything you can think of that hasn’t been yet invented but you would really like it to have been invented? What kind of a thing or machine or even a law could that be?
I think, personally and practically, the thing I'm most interested in is an artificial pancreas. Something that would kick out insulin without my having to input anything or do any calculations. If it was internal, that would be a bonus. People have worked on it in the past and have come up with some really interesting things in the ninety years since insulin has been processed for human consumption (in contrast, diabetes was known to the ancient Egyptians, according to texts--four thousand years of a disease and the only treatment less than a hundred years old) including constant glucose monitoring systems and insulin pumps, but there is still a need for human input. And that means, eating involves mathematical computations.
People should be able to just eat without having to do maths.
There are probably other things I'm also interested in, but none come to mind at the moment. I'll have to think some more.
