I agree that we need a long-term solution so that we’re not changing the algorithm every few years. The options are to either stick with ASICs until ProgPOW research is done, or just prepare for a POS system that increases coin distribution fairness.
By increasing fairness I’m referring to eliminating the electrical rate discrepancy between larger and smaller miners and eliminating manufacturer pre-mining (Innosilicon). Another advantage of POS is removing the fossil fuel argument against POW coins in general.
If we were on a POS system a year or two from now I would be happy. It’s not perfect conceptually, but its benefits outweigh the negatives of POW.
There are other things to think about: what if POW becomes outlawed by governments after the next bull run. Electrical companies could (and already have) started making policies that specifically target cryptocurrency mining. ISPs could start blocking ports (8333, 8233, 8232), and unfortunately, at least in the US, there is a big ISP monopoly. There are other threats to POW as well.
As the price goes higher leading to more people being involved it will inevitably become harder to make some of these changes.
