Fascinating. Interesting to think on the one hand that people like the Wright brothers made their engines themselves from scratch in their own workshop (which some hobbyists still do), and that the basic concept of these engines - piston driven, internal combustion of fossil fuel - has not changed in well over 150 years, it has merely been refined.
Where's the sub-miniature fusion powered engine for my flying car?!
And uploading all that stuff to Google Cloud? If I were an industrial spy I'd be all over that.
