I am still learning all about it lol in fairness I didn't pay much attention to them on ETH, just seemed like separate environments to put a token within a token so I dismissed the tech.

It really depends on how its implemented, Could they slap a token on it and monetise it with tokenomics, probably, if they don't how do they achieve scale and source liquidity to get people to use it? How do zk environments become more distributed? Will enough people be running it on their nodes that taking down lets say chainway won't be an issue?

I'm all for trying new things to scale BTC especially when it doesn't need changes to the base layer, but I think I'll reserve my opinion until i've tried it out.

As for smart contracts, I'm not yet sold on what they do that is sooo killer, maybe i'm missing something
