It is quite possible and rather likely that the PSTN will disappear but the
numbering system will not.
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.

As PSTN will disappear, E.164 will also disappear, because there
will be no PSTN operator to maintain E.164 number space.

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