"Astra's founders say that their goal is to become the 'FedEx of space,' a company that will deploy smallsats into low-Earth orbit daily and for as little as $1 million."
Spot on take. Having a completely self-contained smart device has advantages in narrow cases, like portability. Otherwise, if you're doing home audio, there's no good reason to have in all in one box. Make the system modular and thus flexibily upgradable.
Interesting idea. I think it would be more practical if they had parking garages on the edge where folks could still drive places if needed. I'd be happy to use my car much less and be able to walk to everywhere I needed to go normally in the neighborhood. Add in pets and children, and having the ability to use a car whenever becomes a lot more convenient.
