Lately I've been looking at LST and re-staking again, honestly the returns look pretty attractive, but I can't help but ask: where does the money come from?

The basic part is consensus rewards/fees, and the rest is mostly people willing to pay for "safety/liquidity/points," plus some leverage and maturity mismatch flavors...
It easily turns into a sentiment game where everyone is just waiting for the next sucker to take over.

The risks aren't too mysterious: contracts, oracles, de-pegging, redemption queues, plus re-staking turning the original chain risk into a chain of risks, and if any link breaks one day, the reaction will be very quick.
I see that now AI Agents and automated trading are getting lively again, with both narrative hype and frantic on-chain interactions.
If security isn't tightly controlled, problems could be much worse than a few manual clicks.

I'm a perfectionist, so it's even more awkward: I want to wait until I see the position distribution, liquidity, and redemption mechanisms clearly before jumping in, but usually I only dare to act after the hype has cooled down...
Forget it, I'll start with a small position to test the waters—being able to sleep well is the most important.
