You're right in that nothing lasts forever. That was a poor choice of words on my part. However, the most likely scenario I see occurring is that CN ASICs fail at a gradual rate and so there will be a long period of time where hashrate becomes more concentrated among fewer machines - perhaps entirely on a Bitmain pool, which would be even worse - yet is still too high (relative to DERO's price) to make mining it with a GPU worthwhile, much less attractive.
Even if that interval only lasts a few months it will be a serious vulnerability for the network, and that was more or less what I imagined happening when I made my earlier post.
On a theoretical level, I see your point. I'm just not sure how likely that scenario is. It does make sense in that regard I just don't see it as probable, personally.
Perhaps, but what is certain right now is that if a CN ASIC fails you can't buy a new replacement for it. If DERO - or other CN coins - become wildly popular in the future (as defined by market cap), then more CN ASICs might be produced, but there could still be a long lead time between an upswing in price/market cap and an ASIC manufacturer responding to it. Furthermore, another situation all but guaranteed to happen at some point is DERO not being the most profitable CN coin to mine so most of the ASICs switch away from it; that would also cause a collapse in hashrate that could be exploited.
Basically, the point I am trying to make here is that sticking with an ASIC'ed algo does not
necessarily improve network security. The only (current) way for coin devs to truly secure a consensus-based PoW algo is to hold the majority of hashrate themselves, otherwise you are trusting strangers to not gang up on you (which kinda fails the "trustless" criterion, eh?).

On a separate note, I caught most of the wild pie-fight on Discord today between a bunch of TurtleCoin supporters and --Serena--. Rather than editorialize I'll just reprint one of her comments and let the gentle reader draw his or her own conclusions:
I can say one thing for sure though
Turtlecoin is a shitcoin, that is all.
Lol, stay classy, --Serena--...
