I can't define what it means to be "Einstein". I can only say that "capacity for knowledge" in a "healthy" human brain is well beyond what it could ever be exposed to in a lifetime. Note that when I say "capacity", I thinking in terms of a computer harddrive(which is questionable). No "healthy" human being can fill up their brain within a lifetime.
This discussion is pretty difficult in that there are things we can't define. I don't even know if we're all talking about the same thing when we say "knowledge" and we can't define "healthy", and the term "capacity" for the human brain is assuming we all believe the human brain really does have a limit. I can only assume there is some kind of limit in the same way I assume if I traveled in a straight line forever I'd eventually reach the end of the universe. It's just imcomprehendably large and nothing we do in a lifetime, currently 100 years or so, will reach that limit.
