ASICs are going to rid a large amount of pools. GPU mining and FPGA mining will fade out, because the value returned will be so minimal compared to these monsters. There is a finite amount of bitcoins released for a set amount of time. The power consumed/bitcoin return ratio on GPUs/FPGAs as the difficulty rises due to the ASICs will just leave people frustrated. GPU mining had one benefit. Once you gave up, you coul…
I think the tech has gone CPU > GPU > FPGA > ASIC.

I think the tech has gone CPU > GPU > FPGA > ASIC. Makes me wonder what will come next.
You do realize the whole premise of an application-specific-integrated-circuit is to do one thing the best. If properly architected, an ASIC that does the most SHA hashing with the least transistors will be the best miner, inherent to the technology.
Doesn't the reliability of bitcoin stem from it being very difficult for any one entity to control over 50% of the computing power in the network? News like this makes it seem like a state sponsored actor could do it without too much trouble.
Not quite. The difficulty is set to average that a new block is found approximately every 10minutes. However, if lots of capacity is added all at once, the difficulty might not change for several days, and blocks will be generated at a faster rate during that time, as it is only updated every 2016 blocks. https://en.bitcoin.it/wiki/Difficulty
Somewhat splitting hairs... it's adjusted to 10 minute blocks, and there's also a huge variability in how frequently they are discovered. Even if the average was 10 min, there are blocks found within the same minute, or with 30+ minute gaps.
Variability wouldn't matter if the average over time was alright. But it's not just spitting hairs: BTC generation is significantly ahead of schedule. https://news.ycombinator.com/item?id=5780861

It's easy to get over 50% of the hashing power: just buy it. Bitcoin is especially vulnerable during technology transitions; e.g. in July 2010 a single Radeon GPU was more powerful than the entire Bitcoin network so you could have performed a 51% attack for $300 plus some epic hacking.

That doesn't mean the designs cannot be improved... And once somebody releases an improved design, the older ASICs become far less useful.

Maybe someone will figure things out at the circuit level to get hashes out faster. Or figure out better ROMs (with fewer transistors) to store the 64 32-bit fractional parts of cube roots of primes. Or, someday, someone will come up with the coinotron, which, like a transistor or memristor, would be at the boundary between chemical and electrical engineering, targeted at the bottleneck in the hash.
