Why is there such a lack of nuance when discussing AI and the future on investing threads?

I've noticed on this and other investing subreddits that any mention of AI companies gets automatically upvoted if you say the key words "AI will never be profitable/viable" and downvoted for literally anything else.

Whether we like it or not, it seems pretty obvious to me that some form of AI is here to stay. Whether or not it ever becomes profitable or replaces everyone is something we won't know until it happens, but people seem so confident in their stance and will not stand for anything in between.

I think any reasonable person should agree on 2 things:

1. that we have no idea if AI will be profitable or not

2. anyone who confidently says either it'll never be profitable OR that it will replace people has no idea what they're talking about because we don't know the future or how AI will evolve

I would like to iterate that I have no idea whether AI will be profitable or not and I'm smart enough to admit that as should literally anyone, but seeing such confidence in so manty people saying something will never work is frustrating on a subreddit that's supposed to have open minded people.

I know you people are out there, so please tell me why you so confidently believe AI can never be a viable business. Is it a fear of being replaced such that you convinced yourself it'll never work? Do you believe models will never advance past where they are today? Some other reason?

Again, since I know how Redditors work, I want to iterate that I am not taking a stance and I have no idea whether AI will be profitable or not, but seeing so many people be unable to see past their own argument is mindblowing.
