More "let's welcome our new Chinese overlords"

I'm referring, only partly ironically, to all of the tech world turmoil that the Chinese AI company DeepSeek has caused in the last week.   This Newsweek article summarises it well, I think.  

It does strike me as a little odd that tech stocks should tumble on the basis of unverified claims regarding the cost and type of chips used to create it - but I guess the dramatically lower cost to high end users factor alone might convince analysts that there really must be something to it.  (It might also be seen as a good excuse to put a correction into an overheated bubble, perhaps?)

Also: I still don't really understand how you make a heap of money from releasing an open source product this way.

But anyway, on the weekend, I downloaded the app (on Android) and in my limited use so far - yes I'm really impressed.

I have mentioned more than once that the most useful AI product I have found is Perplexity, because it gives links to its sources of information, making it easy to check that it isn't "hallucinating" part of its answer.   

Well, DeepSeek works in a very similar way, with links provided, and also this (kind of odd, but interesting) feature where it explains the "reasoning" used to give the actual answer prior to composing the answer.

I strongly recommend people trying it.
