AI is expensive. A search on Google's chatbot Bard costs the company 10 times more than a regular one, which could amount to several billion dollars.

• Alphabet chairman John Hennessy said an AI chatbot search costs 10 times more than a regular one, per Reuters.
• Analysts expect Google to incur billions in extra AI costs over the next several years. 
• That's because a chatbot query requires more computing power and electricity than a typical search.

Talking to Google's chatbot Bard may cost the company more than just a faulty reveal.
