His attention span.

LOL.

Not being glib. I’ve read quite a bit of Taleb’s stuff and it sounds like an observation based on how long he’s been aware of the market.

Usually if he’s talking about history so if he meant some long term based on analysis, I would expect him to call it out.

Thanks for the clarification.

Market based then, and time scales do matter, as we see now with the issue to entire generations in finding affordable housing.

The problem with a market based approach is that when things genuinely do become limited, people substitute or do without. And thus market watchers like Taleb don't notice that something that busted is now fully bust (or has become a luxury item).
