You don't need to understand how the engine works in detail, but in general, it's useful to know which operations are expensive, performance-wise, which are cheap, and what triggers them. For example, you want layout recalculations to only run when they're actually necessary. Or, if you want to move an element around, you should use transform instead of position as transform is "free" because it's a simple matrix multiplication that the GPU does anyway, but position might trigger a re-layout every time you update it.

Ah that's more like it.

    I doubt it, sounds like confirmation bias.

This is the difference, and why we can never understand each other.

I couldn’t care less how much customers like something; what matters to me is if it’s technically perfect.

This is also why I will never be happy at any job, because it turns out technical perfection doesn’t pay the bills.

    I generally agree with you, but if you only care about technical perfection, it can happen that something is "technically perfect", but insufferable to use.

    For example, I'm sure many of the common command-line utilities are considered technically perfect by their developers, but outside of some common use cases you've memorized, they are all a pain to use because of how undiscoverable CLI is by its nature. The "wrong input, go read some manuals" style of error messages doesn't help either.

    I myself always start from user requirements and work my way down from there.
