Sooner rather than later doesn't matter.

What is most important, is that it's done *right*.

Look at TCP/IP and GPS. They took 20-25 years to become economically viable for businesses and consumers. We're in year 11 of crypto.

Put the foundation in correctly now, and let the rest take care of itself.

True..... but one can dream. Imagine Segwit at 90%. 
His new development is even more interesting and needs adoption sooner than later.

That the mempool is down 90% since Dec 2017, yet transactions are at an ATH, suggests that Segwit is working just fine, even at 40% adoption.

Hope this gets adopted faster than his other development: Segwit.
