it always can be argued, what has really happened to availability, but somehow I feel like saw this coming, though I wasn't quite sure how it would be visible to consumers.
almost exactly year ago, Bloodbob asked me via PM about how I see the situation, and I replied that fab processes can't keep up with the development of the chips and that must be visible somehow or other. (unfortunately I have lost my reply, and I only have the original PM from bloodbob left.) In this case, it's more like visible as problems to deliver enough working high end chips than that lines wouldn't be able to make them at all. I am not sure if the yields are good enough or if the manufacturing capacity is just lacking the need (or perhaps both partially.), but in any case, the situation to consumer is pretty much same.
Also, anyone ever thought that both big ones are trusting single semiconductor manufacturer? if anything troubles arises with TSMC (strikes, natural catastrophes, etc...) what happens to availability of chips? How big storages companies have to keep up if something happens?
