Tools should enlarge us.
Technology should extend our agency, curiosity, memory, and care. Handing those over to it instead is using the tool backwards.
Satnav is the small, everyday version of the problem. Use it and you will get where you are going, on time, by the fastest route. Use it every single time and something else happens: after a few years you cannot cross your own city without a phone. You did not lose the skill. You never built it, because the tool was there before you needed to.
So keep the satnav, and also turn it off sometimes. Drive home the long way without it. Walk somewhere new with the phone in your pocket and see how far you get before you have to check. Get a little lost on purpose, somewhere being lost costs ten minutes and nothing else. The aim is to have both the bearings and the tool, so that the tool is something you use rather than something you cannot do without.
The same test applies to everything else. A calculator is fine if you can still tell whether its answer is plausible, and a search engine is fine if you still remember things. An assistant that drafts your writing is fine only if you could have written it yourself. The tool should leave you bigger than it found you. When you notice that a capability you used to have has moved into the device, that is the signal to turn the device off for a while and get it back.
