30 years ago, a single computer sat in the corner we could sometimes use it to play "educational" games. Not learn how to use computers or even type, both of which would have been useful life skills. Not how to program or actually educate.
Now, my son's whole class has laptops (progress!) and what do they use it for? To play Prodigy, a shitty "math" game ("What's 4 + 3? Your attack is successful!") and nothing else. Kids are bored of the shitty game, which pushes kids to pay for microtransactions during class, but they aren't allowed to do anything else on the computer.
My son wants to work on his Scratch game? Nope. Wants to research for his science report? Web access disabled. This has nothing at all to do with computers in classrooms and everything to do with top down educational policy driven by administrative greed.
