Someone asked if the US economy could be damaged by the high valuations startups get now, and I realized there's a natural protection against this. All the growth is concentrated in the big hits, and they are exactly the companies most able to grow into an "excessive" valuation.
Paul Graham: High Startup Valuations Concentrate Growth in Companies That Can Justify Them
Positive users agree with Paul Graham that high startup valuations are justified by power-law winners creating most value, while negative users criticize them for sending bad signals outside tech hubs and relying on hindsight.

It's certainly true that a startup can be damaged by raising too much and/or at too high a valuation. Raising too much makes you spend too much. And a high valuation increases the chance of a catastrophic down round later on.

So high valuations can be a problem, definitely. But the startups that matter most for economic growth (and investors' returns) are exactly the ones that high valuations are least likely to damage.

@paulg without any horse in this race, what does bother me is it sends a bad signal everywhere else outside sf. also coz how easy it has become to game the revenue (shadow deals)

@paulg Just like it's better to be overrated than underrated.

@paulg wont most small ai companies fail and the big token providers will see a dip in revenue because of it?

@paulg LOL right, but what about all the techbros who will never come close & must live off their parents, that's just extra fuel for them

@paulg Let’s hope hyperscaling works out as everything is inextricably linked.

@paulg The big winners create 90% of the value

@paulg Exactly. The power law protects the system.
Bad valuations die quietly.
The big winners are the only ones crazy enough to grow into yesterday’s crazy price.

@paulg In past cycles high valuations haven’t caused economic downturns, but they have magnified their effects.

@paulg the valley has been explaining why this time is fine since 1999

@paulg Exactly. High valuation is not the poison.
The poison is when it makes the company spend like the future has already happened.
Reality always comes back to collect.

@paulg It's only damaged by high valuations because people take forever to IPO, therefore depriving the public of any meaningful bag.

@paulg I also wanted to ask this from an expert like you, can AI bubble break like dotcom bubble ? I am not any expert, so question might be dumb

@paulg Down rounds really are *that* bad?

@paulg if the big valuation startups all depends on rented infrastructure that can be outdated in few months the natural protection may not hold.

@paulg Smart observation, big hits always find a way to justify themselves.

@paulg come on,融资估值像健身照:拍得越猛,后面越怕称重。

@paulg Markets reward the companies that keep creating real value.
Strong businesses have room to grow into ambitious expectations.
That’s why long-term execution matters more than short-term valuation.

@paulg Not every advantage becomes a liability.
The strongest businesses can turn high expectations into real growth.
Execution is what determines whether a valuation becomes a burden or a milestone.
