I want email to stay at least for work related. Imagine your employer shifts to WhatsApp or signal. Asks you to code shady stuff. Even if you resign, there is no proof your manager knew it if your official mobile phone was wiped. Think about harassment from senior managers. All these go undocumented. This is why I prefer my email from and to every one in office to be plain text. No PGP. I am German; do not care Hillary or Trump - but if Hillary had used signal. May be things would be different!
