They only work on the most basic of use cases. The moment you want to get real work done they just get in the way.
Disclaimer: I used to work for one of them (Mendix)
VB6 was so horrible and productive at the same time. Single person could build an app in days that a team of 10 would struggle with today.
And a group of 10 could bring said app to a stretching halt.
So many memories, good and bad.
Was at a company that invented a visual programming tool and forced development to use it.
Several flat out refused. We all went on with our careers. The people that used the proprietary system still work there, not then a decade later. They hated the tool then. But they have no marketable skills set at this point.
Edit: Stay classy HN
But it seems though even mentioning that perhaps structured data is a better way to store code makes most programmers really angry. At least that's my experience.
I feel like the insistence of text based programming languages just leaves the industry completely mired in the mid 1970's.
