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.

Replying to @elonmusk @ashleevance
I really think you’re going to want a 10x energy density, electrofuels like solution

10x energy density is not needed due to the efficiency gains made possible by electric aviationpic.twitter.com/OhYjHTfrbX
