And now for 50 years worth of security updates for a phone like that. Not to mention what people might do with throwing a phone in the trash or something
I'd take it if it was a reasonable price, like 1k, and if I could just swap it into new phones every time I upgraded.
The problem is, power requirements tend to increase as computation power increases. And no doubt battery tech will improve in those 50 years.
They already sell phones over 1k that are expected to last ~4 years. You'll need to tag another zero or two to that price to incentivize manufacturers.
They could do it to gain market share.
