Human babies develop so slowly compared to other species.. why? A baby giraffe practically gallops out of the womb but a human baby can’t hold its head up.. what aspects decipher the speed at which a newborn develops?

I forget where I heard it but one explanation is that human babies essentially have to be born a trimester early because of the size of our brain/heads. If a baby was born old enough to be semi-self sufficient they wouldn’t fit down the birth canal. (Jokes about that being at age 30, aside).
In addition, as a species humans have developed a society to care for young so there is little evolutionary pressure for self sufficiency at birth.
I also wouldn’t say babies are useless. They’re extremely effective at turning money into poop.
