You're 100% right, with easily accessible technology people don't retain the skills that are supplemented by that technology.
As a kid growing up with the advent of computers it was all jank, you had to know how to fix and diagnose both hardware and software issues, but you still learned to do it with limited resources and (in my case) even very limited English knowledge. I had, in fact, learned English mostly because of my interest in computers and games, and I learned programming also because of my interest in games...
I was thinking that "oh wow the new generation will have it so easy, they will grow up with reliable and easier to use PCs, they'll know even more than me and be so good with it!" and it's the exact opposite. Because it's so user-friendly and readily available they don't need to learn to fix anything, they can just buy it. They don't need any skills that are deeper than basic usage. And that's how you get kids today who don't even know how to turn on a PC, let alone use a word or table processor - because they have iPhones and iPads and never needed anything else, they never found it groundbreaking or useful.
So yeah, not only will they be less knowledgeable, they won't even bother thinking or checking the answers, because the AI will be right most of the time. I'm actually kinda worried that this will make people really easily manipulable.
