>nowdays sociopaths who arent very able whit "technology" (kinda how it is also said that Win10 mockups were meade in powerpoint) are taking over the project management of IT companies
Not surprising, since these kind of people already took over the job of teaching/writing about project management.
I have never heard of any project or company actually using UML. It's one of the worst things I have ever had to study, so pedantic that it's more distracting than useful. I feel like most literature focusing on software project management is done by bored academics who invent increasingly more pedantic solutions to non existent problems.
SCRUM, UML, AGILE, PAIR PROGRAMMING... if anyone unironically uses these words in my presence I will fucking spit in their face.
