Microsoft looks to revamp AI reshaping search as Google calms investors

Alphabet Inc.’s Google and Microsoft Corp., whose quarterly earnings each got a boost from their established search and cloud-computing businesses, used their time with investors to emphasize what’s next: artificial intelligence.

In their respective earnings calls on Tuesday, the tech giants, which are becoming rivals in the competition for the future of search, offered up starkly different assessments of just how much disruption is in store for the market. Google executives encouraged investors to trust in the company’s long track record as the world’s leading search engine, and framed AI as just another shift in its constantly evolving business. Microsoft suggested that something much more dramatic is underway.
