I can say with certainty that opioids are addictive. I can also say with certainty that doomscrolling is pretty far on the opposite end of that spectrum. I have yet to meet someone who would steal copper pipes off of an abandoned building or sell their body on the street for a few scrolls of tiktok.
But why do you get out of bed at all in the morning? What drives you to exist...are those reward systems in the brain addictive? Why are you sitting at your keyboard right now arguing with a random stranger on the internet?
Are you procrastinating something else you should be doing instead...and is that Hackernews' fault or yours?
You'd like the goalposts to sit closer so its easier to offload responsibility onto abstract external entities.
I'm arguing this doesn't change who has to be the one to close the app, shut off the TV, turn off the video game, close the bag of candy and take risks in the real world.
