Serious answer for number 2: it's like why junk food isn't as good as a nice salad mixed with your choice of protein and seasoned to deliciousness. It isn't sustainable or good for your growth as a person.
Finding something that helps push the brain chemical buttons AND helps you be mindful and not get lost in the time isn't easy but it is super helpful.
Definitely true which is why I didn't want to make any blanket statements. I'd even say it's so subjective that the meme of the therapist spraying water while funny is hopefully just a meme/joke.
But another way to look at it might be to consider how you can get the happy brain chemicals in ways that don't involve tech all the time (he said as he typed it on his phone he's been on too long)
To an extent, sure. One's preferences are always going to be subjective, but snorting coke also releases dopamine but is very clearly not a good nor sustainable way of attaining it, even if it might subjectively be preferred by some.
