The entire Internet is built on swapping between fibre and copper. There's less and less of it now that fibre optics have reduced in complexity and cost so that they can be run into people's homes but up until probably 10-15 years ago almost the entire world's Internet travelled the last few miles on copper lines while the core infrastructure was fibre. ISDN, ADSL, VDSL are all built on media-converters in one form or another. So is probably around 75% of all LAN technology today because UTP ethernet is so much cheaper and easier to build than fibre ethernet LANs.

For context: He’s talking about the communication system between airports. Apparently it had been over copper, but now they’re taking bids to make it all fiber.
But, as usual, he’s an idiot who has no idea what he’s talking about.
What a stupid timeline
Obama and Clinton are Ivy League educated and they very likely wouldn’t know either, but they wouldn’t venture to pontificate on it because they aren’t narcissistic liars. Well, not especially pathological ones, anyway. Trump can’t help it.
Absolutely. “Better to say nothing and be thought a fool than to say something and remove all doubt.”
A cue to whether someone is educated is how hard they try to fight experts in a field they know nothing about.
People with expertise in one field tend to respect those with expertise in another.
They however listen to advisors and experts.
