I wrote an entire book about how to get real value out of AI at work and my *first* piece of advice to anyone on this subject is to recognize where AI is *not* appropriate (spoiler -- 95% of what we do) and *avoid* trying to use it there.
"The real tragedy isn’t that students use ChatGPT to do their course work. It’s that universities are teaching everyone—students, faculty, administrators—to stop thinking. We’re outsourcing discernment."
AI is Destroying the University and Learning Itself
Students use AI to write papers, professors use AI to grade them, degrees become meaningless, and tech companies make fortunes. Welcome to the death of higher education.

It rocks to tell people their shit rocks. Every single person who has ever been nice about my work has been appreciated for doing so. I take time to say I love stuff and it’s always the right time to remind somebody you value their work! You don’t need to get into detail either. Just say it rocks
I’ve sometimes fallen into the trap of thinking that complementing a creative person for their work is less sophisticated or desired than discussion or debate about it but very often the best thing you can say to them is hell yeah and that doesn’t make you dumb it just makes you nice

All of which is to say -- what are the odds these announced investments are going through?
“To recoup their existing and announced investments, AI companies will have to bring in $2 trillion, more than the combined revenue of Amazon, Google, Microsoft, Apple, Nvidia and Meta.
“And they have to bring in that $2 trillion before all those GPUs burn out…which is, again, about 2–3 years.”

This is something I struggle with as a journalist who writes a lot about AI. I have written whole articles about how AI is a misnomer! But I feel powerless in the tides of linguistic drift.
Has anyone else who writes about AI found ways to usefully (and regularly) distinguish types?
