Autocorrect can be annoying when it happens to you, or amusing if it happens to someone else. But one thing that appears when you look at amusing autocorrects on the Internet is that you often find someone saying “it’s the phone” or “the phone is doing it”.
No it isn’t. It’s your fault.
Way back in the mists of time when we didn’t have smartphones and keyboards were big clunky mechanical things (some of us still use them), one of the first bits of IT security advice I ever gave was to read though the emails you are about to send. Whatever means you use to compose a message, there are chances of making a mistake. So what you get in the message you composed may not be what you intended to write.
As a bonus, you get a second chance to review your message to check for “thinkos” (like typos but where your brain comes out with something you didn’t intend).
If you choose to send messages (of whatever kind) without checking they say what you intended, you are responsible for the mistakes.
