It helps to be clear about what this certificate is before judging it, because measured against the wrong yardstick it looks thin, and measured against the right one it is rather well made. This is not a course that teaches you how artificial intelligence works under the hood. It is a course that teaches you how to use artificial intelligence as a set of services, and it is aimed squarely at the beginner or the non-developer who wants to get something working without first wading through linear algebra. On those terms it does a good job.
You start with plain-language concepts, then you build a chatbot in Watson Assistant with no code at all, which is a genuinely smart bit of course design because it gives a nervous learner a working result before they have had a chance to get discouraged. From there it gives you a light Python on-ramp and walks you through calling IBM Watson services for image recognition, natural language understanding, and speech, so by the end you can wire AI capabilities into a simple application. The skill of consuming AI through APIs is undervalued and it is, realistically, how most people in ordinary jobs will actually put AI to work, so I do not dismiss it. The honest problem is the one stamped on the box, this is the IBM certificate and it is built on IBM Watson from end to end.
That means a meaningful share of what you learn is the specifics of one vendor's platform rather than portable understanding, and if your workplace runs on a different cloud you will be translating. Some of the Watson interfaces have also moved on since the material was filmed, so you occasionally fight a screenshot that no longer matches reality, which is more frustrating for a beginner than for an old hand. And because everything is abstracted behind APIs, you come out able to use these tools without much sense of how the models actually function, which is fine if using them is your goal and a dead end if building them is. So I would point a specific person here, a professional who wants to understand applied AI and ship a small project fast, who is comfortable that they are learning IBM's world as much as AI itself, and who plans to treat this as a confidence-building first rung rather than the whole ladder.
For anyone who wants to train models, even an introductory machine learning course will serve you far better.
