[Harry Potter] Apparently my daughter is a witch? Very concerned about this strange low-tech angle!

I live in London, where my wife and I both work in software development. We're not tech rockstars, but we have the opportunity to spend our days with brilliant groups of people who are doing cutting-edge, important work. It provides a good living for us and our daughter, who — oh yes! — apparently is a witch. A very nice man who is evidently a witch schoolteacher come to our house and explained to us that like him and many other people, she has magical powers and will need to go to magic school. He was very kind and reassuring, gave us his full attention, answered all our questions, promised further assistance. My little girl wasn't scared; actually, she seems relieved. Agreed with everything he said, wants to go to the school. We'll probably eventually allow it after we wrap our heads around this whole thing.

But there's something that bothers me and my wife quite a bit. Especially for someone who works with young children, this teacher is *catastrophically* ignorant of anything to do with computers, smartphones, or technology in general. And it's not just him; it seems to extend to this whole secret world. I asked him for contact information for himself, his school, and other people who could help us, and all I got back were mailing addresses! How can you possibly run a boarding school in England and not be reachable by phone? I wouldn't have thought that's even legal! And my daughter herself also wouldn't be reachable by phone the entire time she's away at school. And the teacher seemed to think all of this is the most natural, inoffensive thing ever, often telling me, "She won't need that." He was so calm and unconcerned, I couldn't even get angry.

My wife and I both feel that for my daughter's generation, an awareness of technology, especially coding, is going to be critical in living a life of empowerment. For us, it's for work; for her, it'll be for everything. The idea of removing a bright young girl from that world for several years because "she doesn't need it" is almost cultlike.

What's going on here? Why this strange ignorance? AND IN GOD'S NAME WHY DON'T ANY OF THESE PEOPLE HAVE A CELL PHONE?!

It's not so much an anti-tech angle as the fact that high concentrations of magical energy tend to... interfere with electronics. Unfortunately, this means that any reputable school of magic is simply physically incompatible with your devices. But hey, maybe your daughter will grow up to be the one to crack that problem! Wouldn't that be something?

Furthermore, electronics require a level of infrastructure that such a naturally small population has a difficult time supporting.

More to the point, wizards do *not*, in fact, need many of the conveniences of modern technology, especially in terms of communication, as several means of instantaneous travel are available to wizards, negating much of the necessity for long-distance communication. Meanwhile, if she needs to contact you from school, or if you need to contact her, there are means-- as her immediate family, the statute of secrecy is somewhat relaxed for you. (Consider applying for a variance with the Misuse of Muggle Artefacts Office to allow you and your wife to own a set of two-way mirrors-- your daughter's teacher will have contact information for the Ministry.)

Lastly, and most importantly, wizards have their own economy. Many lucrative careers will be available to her that are not reliant upon a knowledge of Muggle technology (beyond perhaps a basic working level for functioning safely in public places.)
