I hope Amazon now thinks of integrating bitcoin in its payments systems now that Bitcoin has surpassed Amazon

Amazon aren't doing that even if they do they will use apple pay or paypal as an intermediary.
They're too big to experiment on things like that but the good news is, we can use crypto debit card with both service.
We still don't know though, they have so much money that they might think one day to integrate Bitcoin as a payment scheme. I mean if the world is going full Bitcoin then they biggest online payment store should adapt as well otherwise they will be left out.
And Amazon should be the trend setter, that's why I wonder why they are still not jumping on the Bitcoin bandwagon when there are already institutional money flowing into our market. So with that, they could have been weighing their options for quite sometime now and again, maybe in the future they will allow it to be integrated into their system.
