I can't wait man. It's already functional for those willing to play around, just not in a noob friendly way. I have used it for testing purposes and it took me hours to set up a node. Admittedly, I am not familiar with all this technical stuff, so it will probably be done in a quicker fashion if you have the knowledge on your side. I can say one thing.... It will change the way we conduct transactions and completely forget that we are still using Bitcoin. It doesn't feel like Bitcoin at all once you are transacting, because there are barely any limitations. Let the naysayers talk down on LN as much as they want, it doesn't change anything.
I knew the developers were making tests but I did not knew that if you were an advanced user you could play around with it, that is great I will look into it but I will admit I'm not that familiar with technical stuff either, there have been many criticism for the lightning network but most of them come from the miners who as we know have an interest that things moved in another direction, but fortunately the superior option over the table won and when we can finally sen transactions for a low fee in an almost instantaneous way and bitcoin can handle hundreds of thousands of transactions per second then bitcoin will be ready for full adoption.
