Re: AI chips
I don't know much about it but I believe AI is done with limited range floating point representations that are relatively small, like 16 bits or so. Lots and lots of little calculations in parallel on the same chip. GPU's went down the same route so this is just a progression. As opposed to full fat IEEE 32 and 64 bit floats/doubles. Still 10 grand is a lot for a chip even if it can give you bunny ears and whiskers...
We're supposed to be in the middle of a climate emergency and we're being asked to cut our own throats to go carbon neutral, whilst data centres are being stuffed to the roof with these power guzzling things. Some applications are noble, but I suspect 99.999% of them are being used for banal entertainment reasons not for finding the cure to cancer.
I've spent my whole life in technology and I love what I do but I despair at the race to constantly replace and upgrade.
