Programmers and engineers have to apply this thinking holistically. The totality of waiting for slow software is enormous. Performance needs to be given a higher priority by more development teams.

I don't tend to consciously sum all of the time I spend waiting on slow software and slow services. But waiting on slow software impacts my subconscious in the moment, making me feel uncomfortable and frustrated with the system, as if it is antagonistic. If I do spend any time consciously thinking about it, I feel disdain for the engineers and project leaders who believed that what they had produced was good enough to ship.

With the processing capacity of modern computers, waiting for hundreds of milliseconds for trivial requests, or much longer for only modestly-complex requests is evidence of gross negligence on the part of the programmers.
