I can’t say this did or didn’t happen, but I absolutely had ‘philosophical’ thoughts like this as a kid.
When I was ~10 I asked my mom how we know other people aren’t ‘aliens or something’. She just dismissed me as being silly, and I didn’t know it at the time but in retrospect I was absolutely experiencing and asking her about solipsism.
I didn’t know it was ‘philosophy’ but I think it’s integral to how we experience the world and sentience in general.
It’s great for parsing through the enshittified journalism. You know the classic recipe blog trope? If you ask chatgpt for a recipe, it just gives you one. Whether it’s good or not is a different story, but chatgpt is leagues better at getting to the info you want than search has been for the last decade.
