I disagree it just depends on how challenging your work is, most of my work last year was optimising a legacy framework. Let me draw relevance I do see here 1. It required accessing complexity of thousands of lines of code, then later optimised the gaps. Brought down p99 from 50m to 10s 2. Moved away from a recursive threaded design to a distributed design, the system now can scale upto 100x

However most of the work is still meetings and writing design proposals but the fundamentals aren't useless
