You're on the right track. It's a perennial favorite of devs to abhor flakyness, whereas after spending enough time as a tester, you come to terms with the fact that you have to take your tests as a statistical probe because most places test systems are simply not that reliable; sometimes, this is even a design feature.

This experience as a tester is in fact a normalization of deviance from the ideal computation model of a developer. Everything should work the first time everytime from their point of view. The tester sees reality as it is. The Emperor won't fund my test systems sufficiently to service all my customers, so we make do ss best we can. Bonus points in that we get to exercise the edge cases.
