I'm Data Science/ML/AI consultant (trained as a statistician) and have found that most of my job to be completely pointless. This article beautifully captures my frustrations and has helped me sharpen my view on what I really want from my job/career.

anyone who says they work with ‘AI’ must be in sales

Hah. Sadly, it's what I'm marketed as, because that's whar sells.

'Statistics based marketing/lead programs' doesn't sell. 'Cutting edge AI for customer level personalisation' does.
