The issue is that investors expected the legacy revenue sources to compensate for the negative cash flows required for the AI build out. The expectation was that the traditional business would provide a risk backstop because they would be uncorrelated to AI related revenue. The Q3 earnings provide some evidence that the old business may not be the backstop everyone hoped and worse AI may be cannibalizing that revenue. Even if AI manages to compensate, the unit economics of AI is far worse than traditional software, meaning Google et al would have effectively traded a money printer business for a commodity utility, a horrible trade by nearly any standard you can imagine. Of course this is just one quarter but Wall Street is naturally going to hate that possibility being live which it is now.
