So in all practicality, the more specialized the mining gets, the less people can actually start mining, which is contrary to Bitcoin's design.
Even if the ASICs get really cheap, Bitcoin will adjust difficulty to compensate, in a sense, and you'll have to buy a lot of them again.

That reduced quote was what I was interested to see if the trend could be reversed... a design that was so efficient and widely available it was still possible to mine for the masses (as all you could do is multiply at the same efficiencies).
I was unaware they were simply parallel operations rather than solving them quicker. Still, it would be interesting to see if you can solve that operation quicker, rather than in parallel.
The faster you do them serially, the more heat you produce. So a smaller manufacturing process would be necessary, at
ridiculous clock rates. Liquid cooling from the get-go. You'd still need to do parallel; but there will always be room for faster and more efficient.
I've always wondered about this - why hasn't some small group within AMD or Intel or ARM gotten together and done something like this on the side? (If only I had gone into the EE track instead of web dev...

) I think the process is just too complicated and expensive. Until an alternative use of SHA-2 256 hashes could be conjured up, it's a small market and the market cap of those companies is such that it really doesn't interest them. Maybe at
BTC = $1000+?
The Avalon ASICs use a reference spec for their chips, BFLs are custom (correct me if I'm wrong), so there are a few ways of tackling the problem. Would be interested to know what your contacts at ARM say about it and what a 35nm process (or smaller?) would cost--still a "beyond seed funding" project. Maybe make a board/HDK that could be re-purposed for other things but also support a series of SHA-2 256 chips that could be put to mining use as well. FPGA-on-steroids. IANAEE
For some reason (and fortunately for FPGA and GPU miners) there seems to be gross mismanagement at BFL (and convicted felons under employ) and slow-but-steady progress at Avalon (graduate students in China doing the best they can without a solid biz plan).
