Typically job titles as noted in that post accompany some varying level of responsibility and leadership. If this is simply about what title is on your card then OK, sure. But in my experience, many (not all) are seeking the autonomy and influence behind those titles. Einstein had titles too, but it was the influence and work behind those titles he wanted. It's the same for many "careerists", a term I do not like.
I think you're losing sight of the original argument I was responding to: that a main reason for spinning off bits of Google as separate Alphabet subsidiaries was to allow job title inflation for the same role.
There's only one CEO per company, so if you want more CEOs you need more companies. Being CEO of Waymo probably isn't that different from being Manager of the Autonomous Cars Division or whatever, but it sounds more impressive.
