Interesting. It's already looking somewhat less centralised than jonald_fyookball implied in his
Medium post a while back. While the hubs are quite big, there's still a fair number of them and users have the option to switch between quite a lot of different hubs.
It seems like it'll be very easy to set up an LN hub in the future and to use LN in general. User-friendly wallets such as Eclair are beginning to pop up.
I'd still be surprised if the Lightning Network really took off in less than a year, but I do have hope that it'll implemented on major services eventually.
I don't expect anything anywhere near mainstream use until 2020+, by then we will have all the nice wallets we can dream off, I expect around 2021 we will have big companies like Steam, eBay, Microsoft and Amazon ready to take payments. The node count will be somewhere around 5 to 6 figures.
All things considered, LN is still the best approach to the idea of making a decentralized coin viable for the average joe at a mainstream level, without centralizing at layer 0 (see Bcash, others)
