Evolving beliefs about software development?

I spent a lot of time reading this weekend, and it got me thinking about epistemology, knowledge acquisition, mental models, and belief systems.
We constantly encounter, evaluate, and integrate new information into our mental models, whether consciously or subconsciously, but we don’t always take the time to re-examine our deeply- and long-held beliefs in the context of that new information.
I’m curious: What are some beliefs in the context of software work that you’ve re-thought recently? Might be something related to how software work gets done, or about what it takes to become a great software engineer, or even about yourself as a software practitioner.
Vulnerable sharing always encouraged 😀 ❣️
