Point not proven
In Endgame when Tony Stark finally met his father, all he saw was an insecure, extremely nervous version of himself standing before him. Howard Stark thought that he was going to have his first child and was thinking of naming him Almonzo (a mix between almond and Alfonzo, maybe?). Not knowing he was speaking to his son, he asked Tony for tips on how to be a father.
That’s when Tony tells his dad the shocking truth. It wasn’t exactly the best father-son moment, seeing as how Tony practically grew up without a father. He then claims that no amount of money can afford you more time then goes to prove himself wrong by building a time machine.
