I don't think this will move all ordinals spam from main chain to this new satoshiVM, but I am sure second layer solutions will grow and compete in future, so let the best ones win.
Problem with all this solutions can be potential bugs and flaws with code, this is all uncharted territory, but I see satoshiVM has a lot of transactions and activity on testnet:

I'm sad that RGB & Taro don't see as much popularity as the Ordinals or other projects. I found the RGB protocol very promising when I discovered it a bunch of years ago.
I think I saw that RGB is going to work with Liquid Network, and that is gaining more attention with new Aqua wallet that supports both LN and main chain along with Liquid.
