does Lightning Network can work and solve Bitcoin scalability problem?
as far as predictions into the future can be right or wrong, only future will tell!
When it comes to the author of the article, he is a deep proponent of the idea, that lightning is a bad thing for the future of bitcoin. You can read alot more about his position and corresponding posts on bitcointalk. 

There are two things that get repeated over and over again (mostly by proponents of the bcash world): bitcoin cannot scale with lightning, and lightning is centralized ("banking hubs"). 

The current reality looks a lot different: there are more than 2500 nodes and more than 6000 channels open, and for a beta phase software for micro payments I think this is a huge success. I am convinced it can help to solve bitcoin scaling issues. For sure! It might not solve everything, but there are others activities next to lightning, and that's good. But look, this is only my personal opinion. 

Hence I propose to close the question, as it is mostly opinion based, and only time will tell, what becomes true.
