Sadly I think they are about as relevant as photocopy shops and places you can send faxes.

With almost everyone having a smartphone or an internet connection at home you would struggle to run a profitable enterprise. With that said most cafes now provide WiFi so in effect have turned into cyber cafes though I usually find my 4G or 5G if I’m in a coverage area works better than any public connection.
Personally, I haven’t used a public wifi hotspot in many years and can’t say I know where any cybercafes exist today.
