Meanwhile outside the sandbox...

There are actually people working on solving the problems with ASICs and centralization.
Everyone involved in mining would be wise to read up on these activities.

One line of work is a new type of POW algorithm called ProgPOW, which is designed to be much less profitable to implement in ASIC. Hopefully, we will see some projects adopting this.

Another track is the new movement with FPGAs. This type of hardware will fight with ASICs on technical merits and make it possible for the small miner to compete with big farms. The FPGAs can be reprogrammed when blockchains are forking or to mine different algorithms. They are also much more power efficient than GPUs, which will benefit small miners.

Also keep updated on which blockchain projects which are forking to keep ASICs out.
If you do not like ASICs, do not support blockchains that promote ASICs.
And - don't buy ASICs. If you want something more efficient than GPUs, look into FPGAs instead. There are multiple threads on this subject already.
