Hah I knew it exactly. 2019 when my university required to hand in all (raw) data used for creating my thesis on a CD or DVD. I had to buy a new one of these things where you get like 50 disks stacked on a stick (to use 3 of them) and had to borrow my mom’s old laptop, because it was the only one available with a dvd drive. I knew it then and I’ve been right since then: This was the last time.
