Say what, Bard? Join our conversation with Google's new AI chatbot.

Bard is a little late to the chatbot party, but is still important because Google has spent years developing the underlying technology called LaMDA, short for Language Model for Dialogue Applications. This is far-out stuff: Last year, Google fired an engineer for publicly claiming LaMDA was sentient. Google says no, its AI is actually just a "prediction engine," or a very fancy version of auto-complete. It responds to a prompt by selecting, one word at a time, the words that are likely to come next.
