There is no inherent value in having reports or the title of "CTO". Compensation (broadly considered) is the only objective marker of where your career stands*. We primarily work in exchange for money, not for titles or responsibilities that tickle our ego.

If you're earning $300k at some company as a "Ninja Grandmaster (World Wide) Director CTO with 50 Reports", and a "Super Stinky Junior IC" at OpenAI is earning $400k, the IC is doing better than you.

*more precisely, the cumulative compensation at the end of your career, to account for gambits. it is not relevant that you "climbed the ranks" and were bestowed the title of "CEO" at your company or that you were "entrusted" with 5000 people in the org under you - these are strictly elements of some company's internal gamification and person-role-optimization system.
