In software, it's very common to have someone with broad experience in a lot of fields need to jump in and understand these 20 lines of code that are causing some issue because of a change in business logic requirements. To have a temp or newbie be able to quickly close a Jira ticket, you absolutely want verbose, strongly typed, descriptive text. You want to optimize for comprehension by readers rather than convenience for writers.

Mathematics, though, is a language developed by academics for academics, who will spend a long time iterating through variations on the same pattern. When you're years into your post-grad, looking at the same tiny slice of mathematics over and over again, it's obvious what f^(n) means - you've probably written that and thought about it thousands of times - but yeah, it does suck for outsiders.
