How often are you fixing Wordpress sites where people have been using WYSIWYG editors and now all the content is full of crazy HTML and someone ran a bunch of search and replace with wrong regexps and it's just a terrible mess and someone needs to sort it out and that someone needs to know HTML and JS and they need to be focused on the task at hand to make sure they don't delete something that was supposed to be kept.
In other words: there's a world of work out there and nobody loves to tinker with that because it's not "improving complex systems", it's robbing through the sewers with a plunger. I doubt that you'll find plenty of volunteers for that.
The "we'll automate everything" approach is pretty boring in my opinion: we're nowhere close, yet people are talking about it as if it was a thing that's happening until 2030 and we need to be prepared for the societal consequences of it and we need to make changes now (surprisingly, it's always those changes they intuitively like that we desperately need to enact, otherwise everything will be automated and we'll all starve). Let's talk about that when we can actually see it on the horizon.
