 Top four technical courses for all the product managers. Number one, you don't need to know how to code, but you must know system design, system thinking from MIT. System design means you know the architecture diagram to understand the differences between different systems so that regardless of what kind of technology you want to work on, either AI or crypto or API, you know how to design the entire system. Course number two, software architecture. This helps you to understand end-to-end what does it look like to design any kind of software product so that you're able to communicate with the engineering team. Number three, generic AI 101 courses. You only need one hour, maybe two, to understand the basic of generic AI so you can be up to speed about the latest tech trends. Number four, AWS certification. It's only three hours you're able to get AWS certification for free. It's going to help you to understand how most software engineers can run on the cloud, how to make technical decisions, even if you don't know how to code.
