Sounds like Bcasher speech really...
Anyway LN being more centralized doesn't really matter as long as you can still trustlessly use the layer 1. It's more likely that 2 parallel networks will appear within the Lightning network. One that is more centralized and one that is a wild west. There will likely always be at least one linkage between them.
Regarding the big blocker talk, I'm too tired of this. 2014 was 8 years ago.
