For some reason there is this pervasive attitude that it's ok to not be good with computers, the same way it's ok to be bad at math. It is a socially acceptable thing to be bad at, even if you use computers for work every single day. This is paired with the weirdly pervasive attitude that any tool with a learning curve is bad. Throw in the siren song of "good enough", and you have swathes of people who are completely uninterested in choosing the best tool for the job and instead choose the easiest tool for the job.
