I also hadn't realised that undersea cables now use fibre optics but, on reflection, I suppose that using copper conductors would mean amplifying the signal at points along the length.
The world has changed since I worked in telecommunications, microwave and coax when I started was going to be the future. Now it is just something that used to be. Microwave is really only used for temporary links. Just look at the PO Tower in London, when I worked there it had dozens of microwave dishes sending signals all over Britain, today it has none, the technology has come and gone in my working lifetime.
Travelling up the Stuart Highway from Adelaide to Darwin at the side of the road about every 30km was a concrete hut and a solar array powering the coaxial route. These days three quarters of those arrays are empty as the coax has been replaced by fibre which doesn't need so many repeaters and has a vastly wider bandwidth.

Can you imagine how that country could possibly respond without a national grid, water supply, a transport system, GPS and the NHS if it happened to us.
The two scientists mentioned earlier made it work.

Never!
Nope.
That is the brutal reality of life.
