Any successful Lightning Network (at scale) would require a dramatic block size increase. The last (Lightning Network tech) I saw suggested it would need a 133MB blocksize.
Blockstream struck down a modest increase to 2MB in November. They have devs who want to reduce the blocksize. I'm not sure where you're finding hope in LN.
Bitcoin Cash forked off to get back to scaling, and it's doing great. Check out how well the mempool stress test went this past week.
