I do agree that innovation is seriously lacking as of late.

In an ideal world, we would continue to create new and innovative technology every single day, but that's just not possible.
Usually altcoins have a specific roadmap they follow & if they don't follow it or don't have one, it makes them look unprofessional/bad.
So already released cryptocurrencies, probably won't change any time soon unfortunately.
