(you cant just let your mom or sister learn Bash just to install a text editor in Linux right?)
Why not? Are mothers and sisters incompetent or not capable because they are women? Everyone CAN use all that stuff, it is only a matter of time investment. Also, there are MANY sisters and mothers out there who use this stuff much better than you, and many fathers and brothers who are absolutely clueless at it.
His point is not that they can't, but that they (computer-illiterate people in general, regardless of gender) shouldn't have to.
