Basically, there had been an idea a long time ago that trustless sidechains might enable the scaling of some types of activity on the mainchain (just how Lightning scales payments, but not users) and BitVM-based bridges are another step closer to that vision.
Scaling at the base layer is limited, and building layer2s, sidechains, rollups, and other schemes on top of it to allow us to share UTXOs more efficiently might be a way to enable global adoption without making it impossible to run a node at home.
