I really don't understand why we don't think of flesh and blood as a form of robotics now.

A lot of people have considered that for decades, and there have been limited experiments (mostly with insects) -- it's just that it's hard.

For instance, interfacing to biological nerves is fraught with problems. They started trying to in the 1950s, and every decade they got better, but to this day, it tends to kill the neurons in use after a somewhat short period of time -- although they've finally found some promising approaches that may avoid that particular problem.

And so on.

That's the thing about everything you're posting here. I agree that the state of the art isn't good enough, and there are many promising ideas that haven't been developed very far.

But you clearly severely underestimate how hard the science and engineering is. The things that don't impress you, collectively represent hundreds of millions of dollars of work by scientists and engineers who are far smarter than you would be likely to give them credit for.

I think you should take your jaded perfectionist attitude and apply it to making robots of your own, possibly starting with arduino and raspberry pi and 100 year old materials, just as step one of many successive prototypes you would make, each getting closer to your dream.

Progressive refinement is proven to work, whereas attempting to create something large and complex in a single step is largely proven to not work.

For starters I think it would make you more sympathetic to others' work, but in any caes, of course you would be making your ideas a reality to whatever extent, which could only be good.

Lastly, I'm not sure you care, but to us engineers, people who only complain but are never appreciative come across badly. You must have had the experience of being under-appreciated, yourself. It's not a good feeling.
