It's not hard to bump into the 16 GB limit when doing video editing, photo editing, software development with virtual machines, etc. All of those tasks are commonly done by freelancers on-the-go, which necessitates a pro-level laptop. Instead we got a gimmicky touch bar and lost compatibility with decades of peripherals.
Well, this fact coupled with os x being absolutely SHITTY at managing and task-switching when you're doing this, and you've got a good argument for abandoning the platform.
Used windows for 15 years, osx for the last 10, haven't found a panacea between the OS, applications I need to run, and my essential human right to run 100+ tabs. Maybe 32 GB of RAM will do it.
