anecdotally, this is where the famous lack of modern skills comes from in engineering culture. If you keep doing the same things you've been doing, you'll look around one day and see that everyone has moved on.
The market for simple SMB websites is a great example. This went from custom HTML+webservices, to Wordpress, and now to WIX/shopify/square. I'd bet the market for SMB marketing will similarly move to near plug+play google/FB offerings.
However if you started out making websites in 1993, then there are a vast array of products and services one could move into over the last 3 decades.
