I wonder why here on HN, of all places, we think this is some kind of insurmountable issue. Maybe it's just that I'm old. I used to think a gigabyte was an amazing amount of storage and 9600 bps was fast. I wouldn't waste money on a micro SD card that small today, and I'm unhappy when my Internet is getting congested and giving me less than 100 Mbps.

Engineering is what humans do pretty well, and given how successful we've been so far at delivering big power for EVs, I don't see why we can't continue that progression into the future.
