You chose to do it, so it means it was better to you than all other choices. Why would you still do it otherwise?

If your goal is to suffer as much as possible, it does not matter. You are still making choices that lead you to your goal as fast as possible.

It also could happen because tech companies have optimized their products to maximize the amount of time that people spend on them, often in ways that directly result in a worse user experience (by showing ads instead of the most relevant search results, for example).

It’s absolutely not the case that people are good enough in general at optimising their time and lives that the things they spend the most time on are the “best” they could have done.

Most people will readily admit to this, especially when it comes to the internet, and it’s well documented that many people are not happy with how much time they spend on the internet or how it impacts their lives.

Addiction & Tolerance. You choose to take bigger doses of Heroin more frequently instead of living a healthy life. Your logic seems a bit too simple.

Network effects and anti-competitive practices defy simple logic. Intermediate logic is unavoidable, I'm afraid.

Correct. When I spend more time in the bar and fewer time at work and with my family then this is a sign that the bar is more useful and better for me than work and family.

I'm sympathetic to that view, but I'm also aware of a particular way it doesn't explain the world. Often I make local choices that I enjoy while nonetheless regretting them later. Text social networks are the most common way this happens to me. But the other common failure mode was with food.

Without the retatrutide dose I'm on I frequently consume large amounts of food. I love apples, and blueberries, and chicken and rice. I can easily eat an entire Costco bag of Envy Apples at a stretch. Inevitably, I regret this once I have exited my fugue state of food consumption. So why do I do it? My behaviour on retatrutide is far superior at getting me both total content and joy (in the sense of area-under-the-curve rather than point-in-time).

This concept has been explored for a long time[0]. The earliest documented I know of is the concept of Akrasia https://en.wikipedia.org/wiki/Akrasia from the Greek philosophers. But I think any notion of utility must build in the notion of regret and perhaps the bicameral mind and perhaps also the notion of non-rationality. My utility functions for the things I do are not time-translation invariant, therefore I think any model that optimizes for greater content and greater joy must necessarily involve temporally non-local terms. I don't yet have a strong model of this.

But we know this is common to many mental disorders. Part of Cognitive Behavioral Therapy is an interruption of some mental pattern. My wife and I have a game we find amusing to play when we want to overrule the other's temporally local preferences: we challenge the other to a game of rock-paper-scissors to see whether the countermanding applies. When she exercises it, I frequently find that even if I win the momentary desire has passed.

tl;dr: Utility functions have different values depending on the temporal stride they take

0: Recently, Elon Musk claimed that the aim for Twitter should be "unregretted user minutes". Sadly, despite this stated aim, I found that his changes decreased these and increased regret so I had to stop using his platform. I agree with the notion of maximizing (value - regret) expressed in some abstract form, however.

Except social media feeds are designed to addict. A smoker will spend their time smoking instead of not smoking. Does that mean that smoking is good? Why else would they do it, if not smoking was better? It's not that simple. When we blame the users, we forget tech monopolies are spending billions to engineer systems which are stealing our time.

Or that B got worse.

When somebody talks like this, ready to ban social networks, videogames, pornography, the whole internet, and pretty much everything that billinons of people enjoy, by comparing it to gambling, it scares me quite a lot.
