> Does Zuckerberg have some kind of clinical condition where he just can't imagine how other people might see him?

Nah, he just doesn't care. Nothing he does will ever get people (en masse, onesie, twosies don't matter) to stop using Meta products.

People can/will complain about him forever, but shitty people will continue to help him build things, and shitty people will continue to use them.

Well Meta products are decaying like Cobalt 60; people are stopping

and maybe Zuck doesn't think he can do anything about it. There are different theories but i like this one:

-- originally you would put some imagination and elbow grease into using Facebook and get some intention which made it very attractive and interesting to people around 2010

-- then it found a business model which was dependent on your not being able to use imagination and elbow grease to get attention which made it less interesting in general but still somewhat interesting because now you could put cash into the slot machine and get cash out

-- over time they lowered the payout of the slot machine which made the game less interesting and more dependent on 100% profitable scams which could function no matter how bad the payout was; people lose trust in the platform and stop engaging with ads, real advertisers don't want to be seen next to scam ads (lest they be seen as scams) which further lowers the payout and makes the game less interesting over time

-- and now they won't even take your money... so who cares?

Half-ing every 5.2-or-so-years?

Within that order of magnitude. Picked Co60 particularly because it is common in commerce, even I used Co60 sources in my cond-mat theory trainee days.

I think it is more like radioactive decay than say, cheese going bad, but maybe I'm wrong. You can't smell the radioactive decay!

They both captured the early market (inconsistent page style of Myspace, slowness of Friendster, then they acquired Friendfeed) in an early internet - anyone who captures the early market will have THE network effect for decades (plus shadow profiles) as person x joins because person y is there because person z is there - which is still young to this day, and also they apparently used to censor links to their competition

The game is rigged, also Instagram and Whatsapp (yeah, companies get acquired. but WA's Acton was very explicit - "delete Facebook" (also, ever tried deleting FB? almost impossible. more network effects). he was pissed off at what happened)

... the other theory of Facebook's decline is that Eternal September gets you every time. I mean in the 1970s the CBGB and Mudd Club were really cool and they folded up and the scene moved on.

Once I started using the social features on my MQ3 I found it really was Zuck's worst nightmare. I met all these nice retirees who were fun to play Beat Saber with and who would go on cruises and post YouTube links to pano videos they take of the ship.
