It's not an issue of permission, it's an issue of trying to make a computer that's safe for grandma to use. Criminals can and will convince grandma to navigate a byzantine labyrinth of prompts and technical measures in order to drain her bank account. That's the threat model we're dealing with here.
We should have never tried to let grandma on computers. Wait until the genAI revolution is complete (2027) and she can entirely use her voice and an AI agent in natural language to do things. This but unironically. Gate keeping is very good and keeps enshittification at bay. We see what happens when Apple tried to let in too many normies and wouldn't let them get darwin awards.
I helped my mother out with a computer, gave her a mac after she called twic a wee about a windows popup. Eventually she became a grandmother, and later in old age, with dementia she stlll using the mac more or less successfully to google and e-mail.
Intentionality, coordination are important for keeping cognitive faculty.
It all sounds so easy, but letting her send e-mail through voice could create confusing situations.
…you don’t, just like you don’t need the bank’s permission to withdraw funds… but they will still try and stop you pulling out $10,000 so you can buy iTunes gift cards to pay off your taxes.
