Well, I don't really see the point here. The article just describes that it is not as easy as one might have thought to keep ASISs out in the long term with just small changes to the PoW.

But does that really mean to you that it's not even worth trying it? Is it then really better to do nothing and just let everything happen, to have 80% or 90% of your coin being mined by ASICs, meaning centralisation and 51% made easy as taking candy from a baby? For me, this is not the right approach, especially as for the moment, CN-Heavy would solve the problem, you just need to flip the switch.

Yes, we all do not know what's coming in the future, yes it might be (more) difficult in the future to keep ASISs out, yes, it will require some work from devs to keep their PoW up-to-date, but for me, this would definitely be worth the work.
