I agree with you, but most tech support (tier 1‚ anyway) is just following a set of prompts anyway, so it’s barely better. At least with the recording I can abuse it without feeling bad.
I had a problem with Verizon service, and the troubleshooting app (not audio prompts, just answering questions in the app) actually solved it in about 5 minutes, and introverted me didn’t have to do a phone call or chat. So the experience can be good, sometimes.
I have had good luck installing Gallium OS on a Chromebook for my daughter, so you might look at some of the Chromebook tablet/detachable keyboard options. Just make sure the model you get is supported.
