This is something I’ve thought was true for a while, but your comment made me go back and look for decent sources and while I found a few articles bemoaning tech in schools I also found a lot of good-looking scientific studies saying that it’s fine or even beneficial, so I deleted my comment.
AFAIK now, the negative outcomes are when it’s home schooling or COVID-era distance learning and the kid is only doing work on an ipad, so the problem isn’t the tech itself it’s the absence of a structured school environment with a teacher.
I’ve used them for about a year, so far no complaints. High speed, high privacy, only a couple things have required me to turn off my vpn to access them.
