>But how can such person be considered boring?

Consider a continuum from Boring to Exciting. Now place these jobs on them:

- Firefighter

- Rocket Scientist

- Data Analyst

They are more boring, ergo, they are the boring jobs.

Isn't "boring" also a function of "would I see myself doing this?"?

People don't seem to find being an Uber driver boring, because you talk to people all day. This sounds extremely boring and tiresome to me.
