1. You are (likely) not Grace Hopper.
2. Computer science was, in a way, much easier back then. At least very different. Listen to the Brian Kernighan being interviewed by Lex Fridman; he keeps repeating that you didn't have to be as awesome back in his days, using himself as an example.
Saying "If Grace hopper can do it, then so can I" is like saying "If John Carmack can repeatedly write a AAA game (basically) by himself then so can I"[1].
Not only are you not John Carmack, but this is also not the 1990s. Hell, "throwing triangles at the problem" is just not as hard as it used to be.
Marie Curie got the Nobel prize in two disciplines. That's amazing. But doing it in 2022 would be 100x as amazing, making it basically undoable.
[1] Simplifying a lot. I'm aware of the story but I think my point is valid still, since it's "true enough" when measuring Carmack's coding impact.
