I think he worked at google right?
That would make for it yeah. Also probably he is older than he looks like (in fact in recent pictures he does).
If you read that twitter stream, to this day Charlie doesn't consider Litecoin a scam.
But often we need to reconsider what the definition of a scam truly is.
I mean, to make Litecoin he literally took a snapshot of the Bitcoin source code, changed like 2 easily-found config parameters, and launched it. And he admitted that it took him all of like a long Saturday to change and test it. He put almost zero effort into creating Litecoin. He created an altcoin of Bitcoin with a few clicks of a mouse. What he did, anyone could literally do with enough knowledge of the code.
So what part about that process and goal isn't scammy? Today when people do that with the Bitcoin source, we say that they're doing it for scammy or selfish purposes. But for some reason we give Charlie a pass because he's a nice guy, Bitcoin proponent, and no longer holds any LTC. (Little known fact: he once DID hold a metric shitload of LTC and probably made a million dollars selling some before LTC even hit $0.20c)
