> Threads [...] are interfaces for parallel programming Threads are both for parallelism and for concurrency. Threads have been used for decades on machines without hardware parallelism. > are you telling me you never write a mutex or implement locking logic aside from the fact that mutexes vs futures is completely orthogonal to async vs threads, I definitely prefer dealing with mutexes. 99% of mutex usage is trivial and deadlocks are relatively easy to debug. The issue with locks is their performance implicaitons.
