It's really weird, though, that nobody really created a language/tool to bridge these two world. It's always just generating one representation from the other, mostly in a bad way.
I'd argue, that for many problems, a graphical view of the system can help reasoning. But there simply is nothing in that regard.
To be fair, a lot of roles simply disappeared over the years.
Developers today are much more productive than 30 years ago, mostly because someone automated the boring parts away.
A modern developer can spin up a simple crud app including infrastructure in a day or so. That's much much more productive than 1995. We just cram a lot more of the world into software, so we need 20x the amount of developers we needed back then.
