Is the problem social media and/or our phones, or our obsession with dopamine?

I think we all are aware of the doomscrolling problem. This may lead to us thinking that the problem is social media or our phones (or devices bc I rarely use my phone). But, is it really social media and/or the phone that is the problem?

I've used instagram and tiktok before, yet I never grew addicted to them. My habits when using those platforms never included doomscrolling, which may be why I never became addicted. I always found it weird that I especially never grew addicted to TikTok. 

But, there is one platform I had developed an addiction to: YouTube. Many people don't count yt as a social media platform, yet there's people like me who had been addicted to it before. I used to spend hours watching videos, which lead to me procrastinating my responsibilities and neglecting my health. I think all those videos I watched were what's giving me dopamine, which was how I became addicted (at least that's what I theorize).

I guess what I'm trying to say here is that the problem hasn't always been our devices and/or social media, but our obsessed with dopamine. Even when I tried to not use yt, I still find myself having a lot of screentime, and I think it's because I, without thinking, has been trying to get dopamine through other ways, such as scrolling through a website. Realizing this changed my perspective on the mess everyone deals with. The problem has always been our obsession with dopamine.

Now, I may very likely be wrong, so just take all of this with a grain of salt. Obviously, if you need to get rid of any distracting apps, do what you must do. What do you guys think?
