Re: In other words...
"are we going to have flying cars at last ?"
Probably. A few. At least there will likely be some vehicles you can drive to an airport, fly to some other airport, then drive into town for lunch. They'll probably be mediocre aircraft and worse cars. And they'll be expensive. And most likely, you'll need a pilot's license of some sort to fly one.
And they probably won't be battery powered. Fossil fuels have significantly higher energy densities than any battery we can currently conceive and for early personal flying machines, weight is surely going to be critical.
So yes, there will be flying cars, but no you and I won't have one in the driveway.
Which is OK by me. People mismanaging massive vehicles in two dimensions is scary enough. No need to add another dimension to the mix.
