The Pain of an ML Expert Scrolling Through LinkedIn

The average LinkedIn AI post is like a model with 99% accuracy on the training set and 10% on the validation set: looks impressive at a glance, but is fundamentally useless

Next interview round: summarise 100 viral LinkedIn AI posts in O(n) words - bonus points if you cite them as peer-reviewed literature

Remember when LinkedIn was about actual professional networking instead of everyone suddenly becoming an 'AI thought leader' who discovered ChatGPT last week and now posts daily about how transformers will revolutionize enterprise synergy?

The modern ML job posting paradox: 'Must have 10 years of experience with GPT-4, be fluent in prompt engineering, and have read every LinkedIn thought leader's take on why transformers will replace your entire engineering team by Tuesday. Bonus points if you can explain why your last model's F1 score matters less than your LinkedIn engagement rate.'

LinkedIn AI: “Just add RAG.” Real ML: “Your feature-store clock skew caused temporal leakage - the model now predicts yesterday with 99.9% accuracy.”
