Bitcoin is unusuable in it's current form, it doesnt matter how many people know about it if they cant use it.
But their efforts can be used to help altcoins. Either they will be disappointed in bitcoin and leave or they will join altcoins.
Either way it's the altcoins that will benefit the most.
If it's unusable, then tell me why I use it so often and hundreds of thousands of other people use it daily.
Correct me if I'm wrong, is not segwit coming to bitcoin in August? Surely, lightning network will soon follow.
All these things that make bitcoin "unusable" will be solved before summer is over.
