Interestingly the Gemini summary is nowhere near as good. But when it is... how helpful will that be! So many things with a very good summary will save so much time / avoid having to dive into unless truly in need of the details.

But the quality of the summary - and maybe the ability to expand it if slightly more details are required - and the low latency with that - are all super important. In that sense, AI can potentially save a lot of time in getting the right information quickly.

I summarise YT videos with Gemini all the time. You can easily control the length and depth of the summary & get it to focus on particular things etc, before investing time in watching it, only to find out it's promotional, superficial, clickbait, or some combination of all 3.
