Reddit and YouTube are such huge social media platforms that it really depends on which bubble (read: subreddits/yt channels) you're looking at. There's the "AGI is here" people over at r/singularity and then the "AI is useless" people at r/programming. I'm simplifying arguments from both sides here but you get my point.
Some places are more "echo-chambery" than others, reddit is probably an extreme example in echo-chambers. At least the bigger subreddits, smaller ones can be a bit more diverse and enjoyable.
