Yet, the bulk of code written at Google remains Java and C++. golang's approach to uncolored async was decent, yet in the same manner of the language, overly verbose and error prone. Passing channels everywhere gets tricky quickly, and you have to manually ensure that contexts and deadlines are handled everywhere.

Errors in golang do not have stack traces, and wrapping errors is just an error prone way of manually (and apparently nonperformant way of) generating stack traces.
