Good question, I hear a lot of news about lightning system , but I don't see a real progress. Bitcoin transfers are still expensive and slow.
In the last few weeks you can experience that the transfers are not expensive anymore and they are not slow anymore, becuase the current fees are 100 times less then it was at the end of last year (it was about 600 sat/B that time, now a 5 sat/B transaction gets into the second or third block without any hassle and with a bit of luck...) Also, the price of bitcoin has become lower and this also reduces the fees. So as long as the bitcoin network is in this ideal state, lightning network developers has a little extra time to continue the development of the project.
