Even then the problem can be solved by a cheap usb a + c flash drive. At least in offices every meeting room I’ve used for a while now has a usb c dongle for the TV.
HDMI has been less common than usb c on laptops for quite a long time now.
Also, a large fraction of students these days use Google Docs. I don’t have first-hand experience, but I imagine they would either share presentations with the account the shared computer is logged into, or log into their own account on the shared computer. No hardware involved either way.
