It doesn't necessarily have to be leadership. It could be communication, documentation, culture, any number of things. Yes, we are engineers and we work on technical challenges. But nothing is done in isolation, everything is collaboration. The better engineers are the ones that realize this sooner. Even if one person writes amazing code, someone else has to test it, someone has to ship it, someone has to maintain it. These are all engineering problems.
Yes, we all know these things. You're giving me boilerplate management speak. When asked about 10x engineers I think of someone like Fabrice Bellard https://bellard.org/
Fabrice Bellard is a great programmer. For me, 10x is about delivering real value. not just showing off how clever you are. I wish we all knew this but based on my experience that is not the case.
