I previously was supporting a company integration with Appian (building the AWS/Webservices integrating the two halves), which bills itself as a Low Code platform for Business Process Management. And their hello world example kind of worked fine for getting "a business person" to "write code". So the idea was they get these business people to write code instead of developers. But the problem with this platform was that we had to eventually get full time software developers (so no cost savings there, but also had the issue of these devs were now niche developers and not learning broader skill sets). Because their graphical development didn't cut it, so they had to drop down into their code proprietary DSL. Then the actual platform was a mess of no cicd, bad disaster recovery, bad monitoring, bad everything. It would have been cheaper and easier to literally just write a business process management from scratch in whatever language we wanted.
tl;dr No code, low code, graphical programming is a fad.
