Plus the inner core is a 1500 mile diameter sphere of a solid iron alloy.

At some point it'll probably be possible, but I'd imagine that's pretty far future territory.

If we ever get to that point, I suspect we'll already be building planet-scale megastructures and won't have any need to be boring holes through the Earth.

Agreed, why drill a difficult hole when you could build a Dyson sphere? My main point was just considering what level of technology it would require to actually accomplish the feat.

It is possible though that some unexpected mechanism would make it more feasible than expected, and communication straight through the planet would have some serious benefits. Especially if it was a straight hole, and light was sent directly through it, without even using a fiber optic cable.
