The fact that you have to explain this is somewhat concerning.

Usually people say that people skills are as important for having lots of impact as technical skills, but the bar for people skills is really low sometimes I guess.

It’s really weird to me that people have such a hard time imagining a world without “scaled agile” and debate over duplo-scale priorities between product managers and nerds every two weeks. In a sane world, these kinds of decisions would not be a pseudo-democratic negotiation.

What about the comment you replied to involves "scaled agile"? I may have missed this.

They are simply saying that any system involving multiple people will also involve people convincing other people to do things.

Do you have a system which doesn't involve that? Does it involve cybernetic implants and hive minds?

Even a 1 person company has customers.

The key word here is “colleagues”.
