I don’t think that argument holds very strongly.

My grandma worked on typewriters, and then word processors in the 70s/80s. She had no problem doing her job.

She’d been using a Windows laptop since the mid/late 2000’s, and it’s always been a huge struggle for her. She’d frequently enable/disable features without noticing, etc.

Her tablet has been, as they say, like a glass of iced water in hell. She is far from a power user, but there is not a single thing she did on her laptop that she cannot do on her tablet.
