Every waking day of every waking use of the devices I have, I find myself constantly fighting a lot with the shitty input and recognition of said input. Things I swore I clicked once but having to click twice or sometimes three times. Such lag input between the last time I clicked and to the time the function of whatever I had to click fucking functioned.
With phones it is obviously worse, with finger input being either too sensitive or too dulled to register, inquiring more touches just to get somewhere or to type something, along with the separated frustrations aside trying to type on awful keyboard interfaces.
On the commercial side, it’s the curse of the pareto principle and the “good enough” approach that is the rational consequence of money-maximizing strategies.
For volunteer/free software/etc. it’s both people being used to working in commercial settings on the one hand, and being ok with scratching one’s own itches first and foremost on the other.
