> n'th degree of performance and memory control, don't pick Python, for instance.

Or be comfortable rolling the critical parts in another language like cython, which I've done and got a 10000x performance speedup because the hot part of the code fit in the CPU cache and the rest was plain old python. There are times to start with something like Go when you're absolutely sure you'll need it, but I rarely regret starting in Python. It's usually easy enough to shift a single endpoint to another language or to use extensions to call into something faster.

You will also rarely regret starting with Go. It's not really a language you would use to have fine memory control and the best performances, so I'm not sure why you mention it as a response to the text you quoted. Go is more like a good balance between low memory usage, good performances, while being a very productive tool.

This is true. I'm a Rust fanatic myself, but I grudgingly admit that I wouldn't start a company with Rust. I just wouldn't trust future engineers enough. Whereas with Go, I'd never write it in my spare time, and I hate the paternalism and limitedness, but those same qualities make it an excellent quality for a company language.

If there's one thing I'd say about Go, it's that it's a language you can roll out across hundreds of junior engineers writing relatively sophisticated code and trust that you'll get a very respectable balance of (a) runtime performance, (b) developer productivity, and (c) safety (memory, thread[0], type, etc).

[0] OK, not in the strict way that Rust offers. But the simplicity and verbosity makes it easy to spot errors, the standard lib offers excellent primitives for concurrent programming, and `go test -race` sweeps up most of the rest.

Only non productive part is the endless juggling of Go modules’ versioning.

I don’t know what you mean by that. The only situation where I spent time fighting with go dependencies is when people use vanity URLs, but that has nothing to do with modules. I haven’t experienced any issue with module versioning.
