Most people do not understand the real business model of social media. But once you get it, everything starts to change.
This includes:
- why they are addicting by design
- why its hard to opt out from them
- why they all inevitably converge to the same monetization model

Social Media as an Attention HFT
HFT refers to high frequency trading. HFT profits off being the "market maker", by investing a lot in CapEx and borrowing a lot of money to provide liquidity.
They don't bet on market direction. Rather, they take any orders that come to them and clearing them for a fee.
The difference between the bid-ask is known as "spread" and that is their margin.
Basically, HFT gets paid for the benefit of adding liquidity to markets.
