Microsoft cofounder Bill Gates says the rise of AI poses a threat to Google's search engine profit

• Bill Gates said in a podcast Google's search engine profits could fall as Microsoft moves into AI.
• Gates said AI is the "biggest thing in this decade" and could reshuffle the tech space.
• Microsoft unveiled an AI-powered Bing in a challenge to Google's search engine dominance.

Bill Gates — the cofounder of tech giant Microsoft — said Google's profits from its search engine are likely to fall in the future because the company he cofounded has been able to move rapidly on artificial intelligence.
