why aren’t there any block/graphic based programming on a professional level?

Question

Pretty much like how scratch works but for actual stuff outside of games.
Thanks in advance.

For PLCs where you have very simple operations and loops, Siemens has Ladder Logic. It works fine for simple stuff, but implementing anything more complicated than
if input 1 then output 1
becomes cumbersome very quickly.
Things like scratch are made to teach you enough to graduate to a more complicated language. Realistically it’s all just methods/functions and the inputs and outputs, but using text instead of pictures.
