Uber COO称未见AI投入产出成比例增长

AI 导读

Uber首席运营官Andrew Macdonald表示,公司并未看到在AI上投入更多成本后,生产力获得了相应的提升。

推荐理由

Gary Marcus借Uber、星巴克等最新案例,对AI的狂热投入发出清晰警告,他认为如果更多企业发现成本飙升却未见实效,那几万亿的估值泡沫可能破裂,这是近期最直白的风险提示。

And some companies more or less already are, implicitly if not explicitly.

None of this should be surprising; I have been pointing out the errors since the week ChatGPT was introduced in 2022, and study after study after study (I will go into this more in a later newsletter) has shown that most companies don’t seen a significant return on their AI investment.

The overall situation is this:

  • Three companies that have not yet shown themselves to be profitable are expected to soon IPO for a total of something like four trillion dollars.

  • Index funds, the staple of many people’s retirement funds, are going to be more or less forced to rapidly absorb these exercises in fantastical thinking.

  • Those exercises in fantastical thinking are premised on the notion that customer demand will be essentially endless.

  • But we are already seeing cracks in that fantasy.

  • If enough customers have second thoughts, none of the three IPO’ing companies will ever hit their long-term projections.

  • In which cases those stocks will eventually fall.

  • A lot of banks may take a hint as well.

  • Get ready for “too big to fail”, and watch your portfolio drop.

Disclaimer: I can’t give you investment advice (let alone tax advice), and the market might remain irrational for longer than any of us can remain solvent.

But I see what I see, and it just doesn’t make sense.
