That was probably supposed to be sarcasm, but yes, absolutely, let's not use a phone for voice calls anymore. That nonsense should have sailed 10 years ago.
I personally have found interfacing with businesses dysfunctional at best today. Auto-mated prompts that send you in infinite loops, email and text services that create async communication making it 10x as long to address my query. The idea that speaking to someone on the phone should cease is laughable.
