> Yes this is the time to buy a domain and own an address for the rest of your life

As someone who does use their own domain to receive mail, I am acutely aware of how diligent I must be to never lose that domain. The chances of someone acquiring access to my Gmail account are far lower than me losing the dotancohen.com domain, especially with the cyber attacks against Israeli assets that have been ongoing incessantly since 2023. One's email is often the gateway to every other online service, via reset password features - losing access is problematic and an attacker getting access is nigh unrecoverable.
