The high concentration of tech companies that are spending on AI are also the ones controlling the narrative including the funding, success criteria, and communication. We are more likely to see minor corrections that effect individual companies but don't impact the market enough overall.
Tell that to their actual customers. At some point, State Farm or Eli Lilly is going to say "hey, we spent $1B on AI and fired 10,000 people. Where's all that efficiency you promised?"
That first sentence sounds so like 2008-land. House of cards is a house of cards. If 1 + 1 = 2, the market will discover it. The 1 + 1 = 3 narrative can only be controlled for so long.
