It's likely that if the lightning network proves too complicated for users
Great point, I added it to my opening post. Most people here don't even understand how LN works. How are you going to explain all this to your mother or grandmother? For something like this to become mainstream it has to be simple to explain and to use and that's really not the case here.
It's the same with cryptocurrency as a whole. How do you explain it to your grandmother?
LN is nothing special and person who already has vague knowledge about cryptocurrency should get the idea without a problem.
Despite its flaws, LN is the best option for bitcoin upgrade we have so far, there is no need to depreciate it.
