tl;dr version: Large tech companies pretend to offer educational material about machine learning, but what they’re really doing is trying to train you in how to use their very specific technology so that they can lock as many people as possible into that way of thinking and doing things, and therefore control the market. A quote:
We demonstrate how the online courses further support Google and IBM to consolidate and even expand their position of power by recruiting new AI talent and by securing their infrastructures and models to become the dominant ones.
Which is fine–all tech companies do some variation of this, and depending on what you’re doing you may need it–but don’t confuse this vocational training for education, because it’s not that.
