My view is somewhat different. Ultimately, all the progress in technology is to make us live better lives, and to accomplish more of what we aim to accomplish. Transportation, energy, computation, etc., are all trying to accomplish the same. Most of these are external to us till now, and we are at the cusp of integrating them into ourselves. I can see why companies are investing significant amount in that regards. 100 years down the line, that&#x27;s where most of our technology will be used.
