This is a great perspective because, if humans acted rationally and ethically, it would be reality.
The problem I have with tools like that is the technical quality of the solution (which Wix seemed somewhat reasonable in its output when I briefly looked around at Wix sites) and the social effects. Putting together a Wix site and buying or downloading/installing a theme does not make you a Web developer.
You're still getting to the end goal of a site, but without the knowledge of how it works and, should it break, how to fix it, it's more of an appliance to you than an environment to express yourself. (using royal you, not you personally)
It's strange to me that people want to be able to "do what the nerds can", but don't want to put any of the effort forth. I would love to be a great drummer or saxophonist, but I recognize it would take years of effort and practice to reach that point. I could compose tracks using synthesized instruments, and that's its own music skill I guess, but it's definitely not the same as playing the instrument.
Which jobs are you referring to that were lost? The dot-com era? As far as I understand, a lot of web design firms still exist, and tons more freelancers make cash through selling custom themes for clients or packaged themes on Wordpress, small client-oriented web apps, etc. And, given that much of the market is on Web tech still, a lot of the skills from 20 years ago translate pretty well and can now be used to make software within the browser. In my own efforts to learn how to make webapps, I've only really had to learn flexbox and grid. Most of my old knowledge has carried over, with some slight modernization tweaks as necessary. It's nice to never need to float a div ever again, haha.
Having good tools that create good work is a goal I think most of us can get behind. The challenge lies in building the tools and promoting healthy culture.
