Technically, the road of SegWit and Lightning is conservative: It guarantees the stability of the decentral network of nodes, which constitutes Bitcoin technologically, while building an optional infrastructure which allows high scaling and growth of use.

The result is, that Lightning made Bitcoin to an experiment with an unknown outcome. It could happen, that Lightning does what it is promised to do and reinforced the needed growth. But it could also happen that Lightning transforms the entire Bitcoin ecosystem in a failed experiment of technocracy. 8/8
