Telephone numbers have a major advantage of being able to be dialed from a 12 button keypad without kludges. China and other countries that have syllabaries rather than alphabets are likely to prefer numbers as a naming system since they use a limited character set that can be expressed directly on a keyboard.
What I expect to disappear is digit-by-digit dialing. Telephone numbers are only dialed digit by digit by the user in exceptional cases today. The need to support efficient dialing in this fashion seems to arise as an artifact of a poorly integrated system.

In the intervening decades, it is probably worthwhile dealing with the reality that PSTN (and hence E.164) exists.
