Doing > Can anyone name a major gadol accepted by all of frum yidden who has/had a smartphone?
Yes, most gedolim miss the unmute button when giving a shmooze on zoom. They know that if you are tool good with zoom, you will not be accepted by “all frum yidden”, maybe just by the rov (like Mordechai).
But, even I – totally not a gadol, and not often accepted by anyone, rarely use phones, and almost never before covid. If someone needs to do work or to write or to search Bar Ilan database, there is a computer for that. If you are so deprived that you can not wait until you get to a computer, and need to punch into a phone with one hand while driving, you are surely not a gadol.
