I say the day Mozilla bends the knee to advertisers and do what Chrome did by phasing out ad-blockers with Firefox. That'll be the day when I look around my apartment and realize "man, I need to start getting into some hobbies now."
To be honest I think I’m nearly already there in terms of using any service that requires interaction with other meat bags. I find having personal opinions that differ (even slightly) from the echo chambers (even when stated as being just an opinion) makes it a constant battle to stay civil, and I’m not sure it will ever get better. Add in all the spam, constant battle against advertising, bot accounts etc and I really can’t be bothered as I don’t really feel like I’m missing out on much.
And the same goes for the offline world too. People need to unplug more.
