Welcome to Tech News Briefing. It's Thursday, November the 14th. I'm James Rundle for the Wall Street Journal.

Chatbots powered by artificial intelligence have exploded in popularity. But how well can they truly replicate human friendships?

We put four bots from the biggest tech companies through their bases.

And then, drones are changing the battlefield in Ukraine,

and even the nature of military units as tech-savvy pilots target Russian tanks and infantry.

We look at how one squadron is operating like a tech startup on the battlefield.

But first, AI chatbots have become startlingly realistic, driven by the emergence of

generative AI and large language models like OpenAI's chat GPT.

Tech companies are pitching the bots as your helper and even your friend, but is their humanity

and Open AI. The results offer a glimpse into the technology's potential and its limitations.

Joanna joins us now to talk about her weekend away with AI.

You can set timers, you can play music, you can do some of these very clear tasks.
