I still get substantial value out of Coursera. I started with Andrew Ng's original Machine Learning course way back when, and recently completed classes that I thought were well worth my time on Claude Code, Crew AI, AutoGen, and MCP.

While not revolutionary, a recent improvement is AI-based review, which is much appreciated for it's near instant review.

From a transformative perspective, I like the AWS Skill Builder SimuLearn classes. They say teaching is one of the best ways to learn, and I found the chat-based role play where you are the expert to be very interesting.
