There's a lot to be done to address digital divide especially for the elderly.
The other week I witnessed first hand how multiple 50-something folks who own smartphones struggled with something as easy as filling a form on a website for making an appointment (in this case for getting a passport) and confirming the appointment by clicking an email.
Or think about the thousands of vulnerable/old people who will die of COVID-19 because they failed to schedule their vaccinations even though they could otherwise access it. A friend who works in Berlin on radiotherapy for cancer patients said lots of them aren't vaccinated because they just can't sign up for it and their doctor doesn't do it for them.
Anything that requires using technology, even as simple as using a browser and getting a confirmation email should be probably be also made available by more familiar/accessible tools such as SMS/whatsapp/facebook or a call center.
