Microsoft's gunning for a far more short-term win: Search.

Bing has been an also-ran in the search world for a decade (single digit % of search volume compared to Google's 90%+), and AI has shown the first real crack in Google's monopoly.

The future is pretty clearly going to be directly getting AI answers to questions and much less looking at a page of 10 blue links and it's still really unclear if Google is going to make the transition.
