Most of the "new" ideas in computing (neural networks, quantum computing, etc.) aren't new at all. Not to mention that Linux and macOS are basically 1960s-style operating systems.
Knowledge of short-term technical details and skills at dealing with brand new systems are much easier to acquire than deep understanding of core principles as well as engineering experience.
Dismissing senior colleagues as "entitled" and their knowledge and experience as worthless and refusing to work with them as a consequence would be a grave mistake.
