Yeah, biggest thing to happen in Lightning development since channel factories.

2. It can be improved, and the developers know what the weaknesses are and are thinking carefully how to redesign optimally
It will take time, but the end product should be easier to use than regular Bitcoin clients. And this will be huge for Bitcoin's competitiveness as a currency, it could be like using gold with a debit card, where the actual bullion is under the complete control of the individual.
