Even before energy density passes jet-a electric aviation will start dominating and completely changing aviation. I suspect at the rate things are going that is just a few years away. One of the massive hurdles holding back innovation in aviation is certifying new engines. Electric motors are so simple that it will be much easier to certify them. Electric will also open up brand new aircraft designs since electric propulsion can go in places an incredibly hot jet engine can't. There are so many advantages that I can't wait for the next few years.
