Lightning Network design is horrible, and it's literally impossible to onboard millions of users without increasing the L1 blocksize to an absurd amount.
The world will likely move onto using rollups on other chains like Ethereum instead, which scale better, and pays gas to validators to get included into the blocks.
Seems like the Bitcoin community is looking into rollups on Bitcoin, but it'll be impossible to get trustless Bitcoin on them, even with BitVM, without a hardfork.
