Id say, learn about bigO notation rather than assume that it's useless. It doesn't require a university degree but it really does help, the more people that have an idea of algorithmic performance both regarding memory and CPU resources the sooner we can get away from all these "web-applications" that barely work but still loads a few mb of unnecessary js libraries. Apart from being annoying this also often leads to unoptimized code that causes wastes large quantities of cpu cycles draining the already feeble batteries of our mobile devices..

So please learn about and/or think about the concepts of bigO even if you refuse to use the math's involved.
