Are TUI email clients dead in 2020?

Drew Devault promotes using aerc as a text email client, especially for working with git patches - https://aerc-mail.org/

Back in the days before the popularisation of webmail I used (Al)pine email client and found it way more convenient to ssh into a box to manage emails vs managing desktops email clients on different local machines.

For the past 8 years or so I've been stuck using gmail and have tried a few desktop clients, all of them feeling a little sluggish (especially electron apps).

Do pine/mutt have real users in 2020? Are they exclusively for the super nerdy who have complex configurations to enable them to manage their attachments on remote servers?

What email client do you use?
