I taught my mum to use the computer. And it took the patient of a saint. I love my mum, but I got very close to breaking off all contact and going out to adoption. To be fair, she got close to disowning me.
At the time I suggested that just as you should never get your husband/wife to teach you to drive (it took her 20 years to take another lesson after my dad tried to do just that), your children shouldn’t teach you to use a computer.
