The digital prescriptions are definitely convenient, especially as you can get them renewed via e-mail to your doctor and thus skip any visitation bills.
I also still remember my amazement when it took me literally 5 minutes to register a new company online, 10 years ago. Not that much different from opening a Twitter account.
An even older system is the tax one, where everything is automated and I don't have to even think about it. I can just annually review the automatically calculated data and press accept to get some money back.
