That is really not the worst thing about ATC. Far from it.
I have heard experienced pilots lamenting that we're still using voice on a scratchy radio, with garbled audio and people accidentally talking over other transmissions both being constant problems, for essentially all vital comms.
While I have no problem with keeping that as a fallback, there's zero reason why we shouldn't have, at least for airliners that have two pilots, a text-based communication system. We can still convert the text to speech in the cockpit to keep awareness the same, but we could play overlapping transmissions one after the other. And think of the other advantages. People wouldn't get callsigns wrong, could be alerted specially when their callsign was being talked to...
It's complicated because we will need to cooperate with all countries, but it's not like we don't have ICAO to work within.
We already have some systems in place for this, specifically stuff like ACARS and CPDLC. I suspect the issue is in congested terminal airspace, though; if you have many aicraft talking to an approach controller it is not uncommon to have multiple transmissoins at the same time.
However, approach phases are exactly the same periods when the pilots probably shouldn't be looking at their FMCs and texting. Voice communication is faster, and so is acknowledgement of voice commands, while allowing the pilots to concentrate on more critical controls. For example, in many airports it is possible to get departure clearances and such via text, but take-off clearance and taxi instructions will still be voice over radio.
