Now that #ChatGPT4 is out, my timeline is full of hyperventilating hyperbole about it "replacing doctors", "writing papers", "acing exams", making [x profession] obsolete," etc.

They couldn't be more wrong.

To understand why, buckle up for a (far too) long thread.🧵 I'll explain the architecture of LLMs & their limitations and give you solid examples of why you - or anyone - have nothing to fear from #ChatGPT & explain my motivation in writing this (besides my sheer irritation at the ignorance of the claims clogging my- and your - timeline).
