Here are the p/e ratios of companies mentioned in the article, after the said "pummeling":
* ServiceNow - 70.66
* SAP - 28.70
* Salesforce - 28.15
* Workday - 73.16
* Microsoft - 26.53
So they range from "a bit high" to "still completely bonkers".
You can't realistically replace that with some LLM solution (in the near-term at least) and they can use the AIs to reduce their costs which is mostly people.
But maybe such a decision was inevitable in their culture. And now it's very difficult to correct.
