Andrew Ng says bottleneck in AI startups isn't coding – it's product management

"GREAT! That means we can fire the people who do the actual work, and replace them with MBA robots, who neither understand nor care about making a good product"

Pardon my pessimism, but in my whole career, I have never met a PM who actual did the work of driving the product vision. Most were just middlemen shuttling information between management, marketing, design, and engineering. Thinking that hiring more PMs would increase the output in the age of AI is such a childish fantasy.

You seem to have a deep misunderstanding of the value PM's provide. What you describe as "just" is a challenging job.

Generally, the vision is set by the founder, and it can be written down in a sentence or two. There's a ton of work trying to translate that vision into something that is coherent across engineers, customers, sales, and marketing.

Also, in product feature teams it is up to the debate whether PMs provide any value, if you put engineers closer to customers. For the PM role to work, they need to convey customer requirements to product requirements. I have never seen a PM do a better job at this in comparison to just sending a TL to a video call with a client.
