Thank you for helping me notice a mistake in double negatives there :)
I am not sure they are ready, nor do I think they want to. But I feel quite certain that they are actively looking in multiple directions to be able to diversify (in particular, I suspect they are VERY attentively studying what Elon Musk does, and not because of some market competitive issue, but because of his (relative) success in solving multiple problems and creating efficient manufacturing pipelines).
Amazon more or less invented the modern cloud computing business model, and they do have a first mover advantage, to a point. But there's so much more to explore in that area for them, they are just starting with the content industry for example, and in the very very beginning of the gaming industry involvement... and that's just online. Then there's the Blue Origin, and all the endless possibilities of orbital economies, whenever that becomes feasible.
But I don't have a feeling they want to step away from the money river of commerce. They are too well positioned to keep wiggling their toes in it.
