There are positive and negative factors presented by mobile platforms: Negative: 1. Highly abstract, hiding away internal functionality. 99% of mobile is GUI.

There are positive and negative factors presented by mobile platforms: Negative: 1. Highly abstract, hiding away internal functionality. 99% of mobile is GUI. iOS even abstracts away the filesystem. Android is more transparent. 2. Highly locked down: walled gardens increase the friction to run custom code. Terminal as an app that can be installed, but on unrooted devices it's almost useless compared to terminal on a desktop. 3. Ergonomics: smartphone keyboards and screens are not conducive for onboard development. Solutions exist but are pretty niche, and most people would prefer attaching a real keyboard. Positive: 1. Arguably mobile platforms have increased the number of coders! The app stores facilitate distribution and payment, encouraging new programmers to make an impact. Desktops are in most cases the actual development platform though.
