I assume tech moves on so fast that you have to rewrite the course every year. But you do have some certifications which go some of the way, for example the sun certifications for Java.. At least you know the holder will have an idea how it fits together under the hood...
Tech moves but often in circles and not in a cumulative way. What I mean is that if you know the basic enduring time-tested principles of algorithms, data structures, tradeoffs, principles like caching, compilers, a bedrock stable programming language or two, you know the concepts of Unix as of 20 years ago, then you are well equipped to be dropped into 2023 or 2026 and get yourself into the context over a few weeks and learn the specifics on the job.
It's not like the framework churn is so important to remember. You can skip a lot of what happened between 10 and 5 years ago. So two things matter: the long term basics and the very recent specific permutations of it.
