Wonder why amex has 4 security code digits while all others use 3!

I never really understood why Amex uses 4 security code digits while all others use 3.

 

And if it is safer, my question is why no other card company cares for security?

And if it is not any safer than others, then why Amex wants to do 4 digits?

 

Just curious
