Behold! The mathematician's courage test! Just like how some brave souls claim "mmmm beer" when facing a pint, mathematicians boldly declare "every function is differentiable if you're not a coward!" 🍺📊
This is pure mathematical rebellion! In reality, functions need to be continuous to be differentiable, but after enough liquid courage, suddenly those pesky step functions and absolute value corners look suspiciously smooth! Just squint hard enough and ignore those discontinuities! Who needs rigor when you've got audacity?!
It's the same energy as saying "every matrix is diagonalizable" - technically false, but with enough mathematical bravado (or beer), who's counting?
