Battery energy density is the key to electric aircraft. Autonomy for aircraft could have been done a long time ago. Modern airliners are very close to autonomous.
cool link! I do think these numbers are very high for those improvements, though, and that probably a generator + engine would be a say to manifest distributed propulsion for example. also, fuel weight declines over the flight while batteries don’t which also hurts batteries...

This generator can self accelerate, and supply electricity indefinitely. No torque is needed to turn this generator, so it is possible to turn very large generator with small prime mover.pic.twitter.com/8xYnpGANmI
