> I’m not sure people are saying that it doesn’t In my career I've meet people who genuinely don't care about performance. For them code either works or doesn't. Back in the days when everyone used bare hardware if a developer would push a change which suddenly requires 10x more hardware (or makes 10x more requests to other's team service) it would break the system and force to do something about it - either order more hardware (takes time) or fix the software (usually faster). Nowadays cloud would auto-scale and such change would go unnoticed, the only difference will be the next month's cloud bill.
