I appreciate Y Combinator at grabbing ppl attention. We need to do more of this ambitious projects. However, I'm rather disappointed lack of even fundamental technical vision. I get that if you shoot to fly in a decade you can optimistically base your model on other technical advances (e.g. better batteries), but too much short-term hype can be deceiving. It will take many years to get there and probably it would be easier to create first small turboprope electric plane.
