Go is only memory safe, not data/resource-race safe across threads like rust. That is an important consideration. Go is not as fast as c. Go is not even as fast as rust. Especially in cases that do a lot of memory allocations. Go is easier to write and compiles much faster. That matters. Dropbox used go and then replaced the parts that didn't run fast enough with rust. So you don't have to do either or.
