Oh null, how I detest you.

Maybe I wrongfully accuse the abstract concept, and should rather loathe the engineers who can't wrap their heads around null despite their heads being a skull literally wrapping fucking nothingness.

Oracle engineers:
"Wait that's invalid input. What do we do?"
"Default the date to 0000-00-00?"
"That kind of looks like a null..."
"Hmm but it isn't *really* a full-on, butt-clenching, hardcore, intrinsic, I-can-taste-it-in-the-air null"
"Yeah not really feeling it either. It's not giving me the typical null-goosebumps."
"Oh, I know! Let's make it a pretend-null, where the actual type totally depends on the layer of the application!"
"Yeah developers love ambiguous random conversions!"
