I agree I don't see AWS and Google becoming simpler, but instead becoming more complex. They are also catering to workloads that are completely different and they really need to have every single possible knob and dial and configuration possible to satisfy these enterprise customers.
Doing what they do is complex and takes a certain skill set, but also doing simplicity right is it's own skill set.
I would say that I would be more worried in the past when AWS was more of a single player, but now that Google and Azure are firmly in the picture, AWS has some real competition in their core market which takes their focus away from us which is great.
Really? I see them becoming more complex as they add more services.
