I can't think of a single production problem that can't be replicated with a unit test. If you're seeing a problem in production, you need to fix it. How do you fix it? You write a test that replicates the problem and then fix the code, which fixes the test.

First you claimed before that unit tests will catch your subtle concurrency bugs before they happen, and that's just not often the case. They are subtle, might involve many systems and weird edge cases and often don't get caught BEFORE they happen. Of course anyone can write a test to replicate the problem after seeing it in production and spending hours/days debugging it.
More importantly, "Write comprehensive tests" is technically a strategy to avoid any bug ever. You can tell C programmers not to segfault by writing comprehensive tests but that doesn't negate the point that the language makes it easy to write segfaults. "Write more tests" is not a rebuttal to saying C makes some classes of errors easy to write. Writing comprehensive tests often takes a lot of time, is often not prioritized by companies, and is especially hard with distributed systems, concurrency, mocks and complex applications. If we just said "git gud noob" in the face of error prone and difficult abstractions, we might as well all be using assembly.
Why are you comparing golang to C?
Your replies here have been less than useless. I clicked on your profile and saw you were "founder and CEO" of some company.
I guarantee you I won't be using your product. Just something to consider.
Thank you for sharing your perspective. I genuinely appreciate honest feedback. My goal is always to add value to discussions, but it seems I’ve fallen short in this instance. If there’s a specific way I could clarify or improve my comments, I’d be grateful to hear it.
Regarding my company, I respect your decision, but I hope that if our paths cross again, I might have the opportunity to change your mind through actions that demonstrate the value we provide to our customers.
Then you have not worked on complicated systems.
Why would anyone even say this to someone? Totally rude.
Reading through the thread, I can tell you have depth of experience.
Perhaps bringing it down a notch could help you connect with others’ perspectives as well.
If people were actually sharing perspectives (like the guy above), that would be fantastic.
