I wouldn't say it's disproportionate. Strong static typing is massively valuable for humans too. Maybe it's just more obvious to some people because you actually can write the same large program twice using the same "person" and a different language.

Previously studies into the benefits of static typing for humans were always a bit flawed because you can't do that with people. And tbh I don't know why but there are a surprising number of people that don't appreciate static typing. My guess is a combination of ego and laziness, which doesn't apply to LLMs.
