Custom instructions / features that are only available on AWS silicon will improve their vendor lock-in. And thus would warrant short term price dumping. Future cost/performance improvements will allow them to raise their margin. Kind of worried what that will mean for the portability of software long-term.

If there are custom instructions added, AWS customers aren't aware of them. Feature set pretty much unchanged too. It's a non-effect on that front.

Are you 'locked in' to intel because of AVX? The cost of moving is recompiling your binary.

What I had in mind is CUDA vs. openCL

Also the field is not static. Amazon does a lot of lobbying. Let's imagine you can check a certain legal compliance box simply by running on graviton.

Or the next industry trend which might be funded and hyped by AWS requires a specific feature for isolation that only really works on graviton.
