Have we been living in different realities? I can't remember any example of companies in the past 10 years that have suffered reputational damage related to their inefficient apps. And there have been plenty of inefficient apps...
Reputational I was thinking leaking data, or generating wrong information for users etc
Plus "next generation projects" that just stall and seem unfinished.
If I didn't see them slam ai into it in weeks just like everyone else I would say they have no product teams or engineers working on it.
OTOH, under what sequence of events would you?
Something gets big / popular enough for you to hear about it, despite having an inefficient app?
It seems exceedingly likely that a large number of companies with terrible apps just never grow... because they have terrible apps.
