I’m currently using a Samsung flip 5. I have it set up to use all my main apps on the outer screen, so I can just have a small screen. Then I have the option to open it for apps that I might want to be on a larger screen.
It’s working out pretty well. Some days I never even use the inner screen.
They could make a small screen phone, but thicker to make more room for a bigger battery.
Fahrenheit makes sense for humans. Most of your day to day climates are in the 0 to 100 scale, and every 10 degrees is a noticeable level change.
Celsius makes sense for science stuff because it’s derived from science stuff, so things like calories and energy work with it. But it doesn’t really apply to everyday life as well. So it actually makes sense to use both units for the things the are good at.
I mean, when that xkcd was made, that was a hard task. Now identifying a bird in a picture can be done in realtime on a raspberry pi in a weekend project.
The problem in the op isn’t really a limitation of AI, it’s coming up with an inventory management system that can detect low inventory without being obtrusive in a users life. The rest is just scraping local stores prices and compiling a list with some annealing algo that gets the best price to stops ratio.
