A man went to a data master and said, “If I work very hard, how soon can I master Data Science?”
The data master looked him up and down and said, “Five years, studying math and computing.”
The man said, “No, listen, I mean if I really work at it, how long—”
The data master master cut him off. “I’m sorry. I misjudged. Ten years.”
“Wait!” Said the young man, “You don’t understand! I’m very smart and I learn fast —”
“One hundred years,” said the data master.
