A built-in scripting language. The TI-83 line of calculators have an app programming language that requires you to side-load code from another computer, but they also have TI-BASIC, which allows you to write a wide variety of scripts right on the calculator itself. This should be standard on all ‘smart’ devices. It’s so stupid to have gigahertz of computing power in your pocket and not be able to do anything without writing the app on another machine.
I know Termux for Android exists and that’s a good start, but I’d like to see something baked right into the OS that has access to all my device’s cool sensors and gizmos. The camera, the microphone, the aux port, the usb port, the accelerometer, the bluetooth antenna… all of those things should be exposed to the user. This would be a really good use case for ‘visual’ programming ala Scratch, since you could assemble a script right from a touch screen instead of having to plug in a keyboard.
I remember in college we took a course on economic efficiency and the short takeaway is “the free market is extremely efficient, but only when the competing parties start with equal resources. the more inequal the starting position, the less efficient the market becomes.” and to my mind that suggests that we should enforce some sort of “rubber-banding” effect so that a company needs to keep competing or else it will “drift” back to the mean over time. Something like aggressive taxes on the uber-rich and comprehensive welfare for the poor, y’know? Capitalism but with safety guards would be pretty cool.
We’ve got a linguistic prescriptivist here! Everyone come and look at the guy who’s sick of stuff shifting over time in response to community sentiment!
