Ha - I care more than you can even imagine, my friend. Thanks for taking time out of searching through Googled postings about everything from crystals to ships of the 1800s to the significance of capitalized letters to accuse me of not caring.

John Nash in A Beautiful Mind: Like a diet of the mind, I just choose not to indulge certain appetites; like my appetite for patterns.

Some would call that willful ignorance. However, that's your choice. Others have alternative choices.

Regarding patterns, design patterns do matter. What is collectively referred to as the 'internet' is built upon design patterns used in the development of software that makes it what it is.

Design patterns are certainly not limited to IT, and exist for a purpose. To ignore them is, well, ignorant. ;-)
