Very interesting and helpful topic, I would merit if I still had it.
From a user point of view sounds like LN it's a potential breaktrough innovation but still with some big issue to fix
(opening a channel 24/7 is clearly impossible, and it's not clear to me how you can manage negative balance once a user wants to close his channel).
Anyway there's a sentence that sounds really disappointing to me
...We cant avoid increasing the block weight in the future...
It's one year since BCH fork, and after all that debate here's the conclusion

.
I quite disagree with it. Block weight should stay 1 MB forever. Makes no sense to me increasing it.
