what happened to our great inventors?

Here is an exhaustive link to one of our greatest minds.
Nicola Tesla. July 10,1856 - 7 January 1943.

The most interesting text arrives late in his career experimenting with the harness of solar wind using HF DC wave choppers to transmit energy that can be received from a tuned device providing electrical work.

Although mankind has made significant breakthroughs in medical science, computing etc I'm certain Tesla would be shaking his head waiting for mankind to stand on his shoulders.

Perhaps the smartest minds are now cutting code for HFT in the worlds largest financial institution's.

Just posted out of awareness as I'm not really asking direct questions.

P. Best wishes.
