> We have Kolmogorov complexity for algorithms but what is the equivalent to measure whole systems? Theory is nice, but we don't really spend enough time systematically or empirically measure how long it takes people to learn various things, or similarly how easy they find making a change to an existing (codebase|project|language|etc). Doing so and just reporting what we learn as an industry would have a ton of value -- arguably a lot more than just coming up with a metric or proxy model of what we care about (how long something takes to learn or maintain).
