Why not just listen to the news? You can listen to BBC on Alexa, along with almost any other news radio station you please. If you want short summaries, just look at the AP.
AI summaries might not be correct or might miss out on important context: in the news, the details are everything. And I doubt Amazon will be paying for the news services they scrape.
Are AI summaries of news really that much better than just listening to the news? Does the AI part mean it's going to try and figure out what news stories I listen to? Or will it just be the same for everyone, and then you might just say Alexa give me the news, and you can program it to give you news summaries from a huge list of available sources, which are not AI generated.
This seems like a stupid product idea, akin to subscription mouse. And I actually like and use my Alexa devices quite a bit (nest thermostat, smart water heater, smart lights, timer, weather, use as a speaker for my laptop), so I think I'd be their target market.
