I’d take a slightly different perspective. I’d like to think that these tools are in some ways “humanizing” - we can offload things that we’re not particularly good at (like memorization tasks) and instead we can use our capacities to do things that (at least for now) we humans are uniquely capable of doing. As an example: Back in the 90’s people knew many phone numbers by heart, nowadays I don’t think people know more than a handful, if that. Does that mean that “phone contacts” are making us dumber? Or perhaps we can use the time/effort/capacity to better use.
