He is not titan in tech industry nor on the path there. Your typical script kiddy does not become tech titan. What it takes to be tech titan is actually irrelevant to whether DDoS is impressive.

> being a business titan requires a different particular set of skills, skills this guy apparently has.

Just about the only thing he has is lack of ethics and morals. Lack of care for harm he causes. Yes, those are necessary to be a tech titan, but not nearly sufficient.

There are many low level guys without much ethics that never ever become tech titans.
