I think agree with the broad, but disagree with the specifics. I really don't think a lot of people at the product level think about products. I really don't think the investors think that much about companies. I think as you move up, the things that separate are (in no order): ability to solve OR mask problems (one of these requires more skill/effort, but to people above they can look a lot closer), ability to naturally or adaptively (this is a fair, but somewhat positive word for this) socialize with the people in that next level, nepotism or blurrier forms of getting your foot in the door, willingness to look the other way (or just be obtuse), willingness to lie (or just be obtuse).

After the IC-level, each level filters less for the duties of the higher role. Even PMs seem surprisingly par at product ideation, vision, insight amongst their cross functional project team members. So many products fail, so many startups fail, so many projects are late, but those things don't seem to be what dictate promotions or investment even when they are specifically that role's role.
