Has the term "CEO" lost all meaning, amid the hundreds of startup founders who have no management experience? Not at all. They're called CEOs because they make top-tier executive decisions and act as the public face of their startups.
Based on the post above, Bahamut's senior title is also a function of the responsibilities he's dealing with - in this case, building the first viable product of the company at an architectural level, and overseeing the completion of major features from start to finish. Just like the crop of startup CEOs in YC, his title has nothing to do with his previous experience. If the leadership of the company has decided he's fit to train new engineers and prioritize tasks for them, the "lead" description is apt too.
I'm sure there are much more skilled CEOs and much more skilled lead developers at other companies, but it's completely impractical to compare people based on internal titles. We're talking about descriptions of an employee's role in the context of his or her own company - don't read anything more into titles than that.
