Google Sheets' =AI Formula
Sometimes I feel like I am living in a cave. Google launched the =AI() Google Sheets formula a few months ago, but they forgot to tell me.

The Naughty AI Worn Around Your Neck
If you remember, a few months ago, I got the Omi device (a wearable AI listening device). It freaked my friends out and sparked many conversations. This article tells a similar perspective about the Friend pendant, which also constantly listens and comments on your day. It has a snarky, judgmental personality, and privacy risks make it more alienating than comforting. Read more →
