Technology is what you make of it. If you want to make it your best friend and your only friend, that's your choice. But I would guess more people would use it as a personal tutor. If it works as well as the demo, this already crushes most language learning apps. Actually the only apps for learning language that it would fail to replace would still be Tandem and HelloTalk because it still can't replicate the nuance of real human interaction.

"Blame the individual" doesn't really make sense when we're talking about things that have a society-wide impact. As an analogue, personally I'm not on social media, but I am affected by social media because everyone around me is on social media and their happiness and wellbeing also impacts me. AI companies need to stop pretending they can just outsource responsibility for their products.

I think assuming people will use it as a tutor/learning tool is.. way too optimistic. A small fraction will, but the majority will just view things like a second language as something not worth learning.
