Not at all; currently I am able to write non-trivial programs in >60 languages and ranging from low-level distributed transactions (did own Paxos already) through 3D visualizations, business software, mobile apps, Deep Learning models and AI, system software all the way to advanced ETL pipelines using imperative, functional, logical, co-routine-based, generics, reactive, declarative etc. concepts and am always on the lookout for a better language as I can't find the perfect one ;-) So I want to understand where Rust stands and if it is meaningful investment to learn it, both programming "pleasure"-wise and business sense-wise.
