Out of roughly 400 billion emails sent daily worldwide, estimates pin actual human written messages at around 10%. In personal inboxes, human correspondence is essentially extinct. Checking my own personal email inbox right now, the entire first page is 2FA, Amazon, some shit from my climbing gym, my car, my employer health insurance, my bank... My spam filters are aggressive and there are literally thousands of unread emails in there waiting for me to click select all -> delete. Even at work the overwhelming majority is automated Jira noise, CI/CD noise, calendar shit, compliance blasts... I have received maybe 2 or 3 actual human typed messages in the last 2-3 weeks.

It's a fucking log dump for machines.
