The eternal struggle between documentation readers and documentation avoiders! While one developer is frantically Googling, checking Stack Overflow, and reverse-engineering libraries, the other calmly points to the documentation that literally spells out the solution.
It's the perfect encapsulation of two developer archetypes: the one who treats documentation as a last resort and the one who's discovered the ancient secret that documentation... actually contains useful information. Revolutionary concept!
The final panel's deadpan "It's docs" is basically the programmer equivalent of "have you tried turning it off and on again?" - simple, obvious, yet somehow mind-blowing to those who never considered it.
