It looks like Go is memory safe for single threads and channels, but not for shared memory between threads: https://en.wikipedia.org/wiki/Go_(programming_language)#Lack_of_data_race_safety https://en.wikipedia.org/wiki/Go_(programming_language)#Lack... > Go's internal data structures like interface values, slice headers, hash tables, and string headers are not immune to data races, so type and memory safety can be violated in multithreaded programs that modify shared instances of those types without synchronization.[113][114]
