Google v Microsoft: who will win the AI chatbot race?

Bard's misfire on launch cost owner $160bn but experts believe ChatGPT is also prone to errors

The James Webb space telescope cost $10bn (8.3bn) to build, but it left Google nursing losses of more than $160bn after the search engine's new chatbot answered a question about it incorrectly.

Google and Microsoft both announced plans for AI-enhanced search this week, taking the artificial intelligence space race into a new phase. However, the launch of the former's new chatbot, Bard, misfired badly when the error appeared in a demo.
