In reply to Miroslav Glavic.

Have you ever built or tried to manage a site on Squarespace?

The design and development industry as a whole isn't going anywhere anytime soon. It may migrate on occasion to other tools that are more appropriate to the task.

For myself, I have been pushing to build more and more sites with GatsbyJS over WordPress for some time now, not because of Gutenberg, instead because most sites don't need a behemoth of software to accomplish their goals. WordPress isn't and shouldn't be the answer to every problem. That's just the perspective of myself and my tiny agency though, ymmv. I still enjoy working with WordPress and will continue to do so post-Gutenberg.
