Whilst voice clearances have been the norm since aviation really took flight, no pun intended, there's much more subtle but crucially important aspects about why this has remained: situational awareness by broadcast.

The critically important aspect: approach clearances and weather reports for a specific aircraft are still useful and relevant to all nearby aircraft. Narrow-casting them to specific aircraft reduces situational awareness for all other nearby aircraft. The system is also tolerant of noise: digital communications can be lost entirely with some degradation in signal, analog voice communications can still be interpreted with a fair bit of noise present (see video below).

The subtle aspect: multi-tasking by using more than one human sense - looking and hearing. People dealing with risky or dangerous situations absolutely should not be sucked into a screen for more than a minute or two to get critical information. This includes to more than one pilot where tasks are being managed and delegated. Most (if not all) controlled or 'aviator-coordinated' (CTAF) airports have a specific radio frequency to tune into to get weather information from an automated weather-to-voice system (e.g. https://youtu.be/HHbrlUPP-4k?t=339).

Whilst it sounds clunky, aeronautical phraseology (https://en.wikipedia.org/wiki/Aeronautical_phraseology) keeps communications detailed but brief and concise.

Digital voice communications often completely degrade for several seconds with a few lost packets, combined with the brevity of aeronautical phrasing can mean critical information is missed. All of these 'old' systems add up to the cumulative safety (https://en.wikipedia.org/wiki/Swiss_cheese_model) and doctrine built by the aviation industry over many, many decades though sadly because a lot of them were written in the blood of others who perished.

Well, as far as I remember, the Link 16 was invented around the 1970s where aircraft could share real-time data in a combat zone.

The weather information can easily be transmitted every minute and it can be nicely visualized in the cockpit instead of being crammed into cryptic abbreviations and ancient codes.

Similarly, we are aware of the precise aircraft location and it's intended course, I'm talking about commercial airlines here, so we already know where they're going and what the approach path will be etc.

I find it hard to accept that we're collecting terabytes of telemetry from engines and all the other equipment on the aircraft, but we expect to communicate the weather and traffic information in verbal ways.

There are so many good ways we can solve the underlying requirements, but I think it's all stuck on the cost of implementation and who's going to be making money from it.
