> one tends to want to work with the code rather than just looking at data I've observed the opposite trend. The more senior people get the more they care about the data and less about the code. Programming = Datastructures + Algorithms But it's the Data-structures/-models that dictate the algorithms and it's the domain and data therein that dictates the model. Most companies could survive their code being lost. None would survive loosing all their customer data. Functional programming is all about data, react is about data, machine learning is about data, google and facebook are about data. Code is an incidental means to an end, in 90% of all cases, except flight software and games maybe, but even there the trend is towards data driven ECS-Systems and "collect all data for a timestep, and execute your flight control program to compute all actuator outputs in one go"-approaches. And observability is one of THE hot topics in the biz right now.
