I’d rather a simpler phone at this point. I don’t think I’ve ever looked at my phone and felt that it’s too small. I can think of other ways that I’d want phones to be more functional, like connecting to external peripherals and a monitor.
Lots of people are excited about folding phones too though, so more power to them if companies are willing to go that way.
Driverless cars can work if enough vehicles are replaced with them. I agree that a few driverless cars in a sea of regular drivers is not optimal though.
