Analog radio and and video signals like VGA, fail way more gracefully and linearly, which is why they're still used in many applications today where rough environments are involved and high availability is desired as a degraded signal is better than no signal at all due to some CRC or handshake failure. Digital connections have a terrible failure model, it either works perfectly or not at all, with little in between. In modern datacenters or in radio broadcasting equipment, you can still find VGA connectors or LCD displays using that signal.
