hi! I work at Temporal. ftr our founders left Uber 2 years ago and Temporal is an independent startup (that is very much hiring) now.
Short answer is yes, we do, but it's abstracted away so you get the benefits (complete observability, retry/resume from failure) without the downsides (handwriting event sourcing logic and storage).
Event sourcing is an impt implementation detail for us, but it is not something we push onto our users. Still they benefit from it anyway. very much agree with your statement. happy to take followup qtns :)
