Why planes aren't electric. Yet.

Wouldn't  cutting a blend of Jet-A with renewable bio fuel across the board be more effective?
(Or fuel from carbon capture that was powered by zero emissions)

What about switching modern turbofan jet engines over to run on H2? (Assume carbon friendly H2 sources)

Why put batteries on aircraft when they would be much better served in ground vehicles that can use them effectively?
(If batteries are a limited commodity that uses limited resources, why use them in the least efficient application?)

Aviation is an industry with a very long technology lead time. (Go look at the serial number plate of the next airliner you get on and take note of it's age.) Wouldn't it make more sense to focus on the sectors that have the best yields? Is there data regarding how much energy capacity the aviation sector needs to electrify and what the projected capacity to be produced moving forward is? What about the overall carbon that will be eliminated by this vs what could be eliminated in ground transportation?

How much carbon will be reduced if we eliminated short hall flights by highspeed rail service? (even if it was diesel electric powered)

I see these electric aircraft projects as gimmicks and or only suitable for niche use cases. (You know me well enough to know this isn't snark... I hope lol)
