Seems like trusting AWS with your data has been a good bet for a long time. They wouldn’t have the size/scale otherwise.
Bezos is not in AI gold rush. AWS is shovel rental.
Also unlike Altman they are trustworthy - a lot of Amazon competitors do run on AWS for decades.
You really don't understand what AWS offers if you think this is what is getting them workloads (including competitors and highly sensitive govt workloads).
