Earlier quoted context omitted.
Land a major deal or create a new product line that doubles revenue? You're getting to the top. From my experience this does not happen at all. Not to underclass developers at least.
At all? I don't know what you mean by "underclass" developers but it is common to see many devs who spearhead projects get higher titles and progress faster. There are many such examples just in SV companies. Part of it is making sure contributions are measured and noticed. People can't act on what they don't know.
True, but if we're going with anecdata I'd point out that it's also common to see devs (and managers) who are taller get higher titles and progress faster too. My own experience is that the correlation is at least as strong as that with getting stuff done.
