Everyone is disconnected from nature,

I live in a city. Me being "disconnected" from nature has nothing to do with my phone. It's a personal choice to live as mosquito-free a life as I can. (Also I just genuinely enjoy living in a city.)

What are you even on about? There's one every day.

Literally the opposite of truth. Modern technology allows me to stay in contact with people I'd be unable to stay in touch with otherwise.

And more. When's the last time you saw a concert?

January.

Everyone is staring at their phones and not even enjoying the moment they're in.

Yeah, because my fucking commute would be so much more enjoyable if I spent it staring into the distance and/or at the other people on the train.

Many are depressed and drowning in meaninglessness.

And you think that's somehow a new development? I mean, I guess you don't have time to think about life if you spend every waking minute just trying to survive as a hunter-gatherer but I wouldn't call that better.

When we look at old pictures of beaches from the 90s (not even that old) everyone appears physically fit, bright, and happy. Did our gadgets really make us any more free, or happy?

Because as a general rule people don't take pictures of unhappy moments. Especially not when taking pictures is actually expensive, film wasn't cheap and neither was getting it developed.

but if the only solution is to go live in the woods, is it really worth it?

Yes.

Fuck no. I don't enjoy literally everything that's associated with living alone (and a small group with limited-at-best contact with the outside world counts as "alone" as far as I'm concerned, I enjoy meeting people) in the wilderness.

You seem to think that because you'd enjoy life as a hermit in the woods everyone would. No. No, we would not.
