This is how crazy rich people spend their money on. I don't think it's an sending error given that it's the genesis block. It's how people make their own history on crypto and how they make themselves seen into articles and news. Maybe the sender wants everyone to talk about him. Like we are doing now, Speculating about why did someone send a hella amount of money to a genesis block which is basically unusable (unless satoshi use it in the future).  Also there's a chance that this is a very old whale who accumulated a ton of bitcoin in it's early stage.
