I'm hopeful for SYCL [0] to become the cross platform alternative, but there doesn't seem to be a lot of uptake from projects like this, so maybe my hope is misplaced. It's an official Khronos standard, and Intel seems to like it [1], but neither of those things are enough to change things.

Someone who knows about this space that can comment on the likelihood that SYCL will be a good option eventually? Cross platform and cross vendor compatibility would be really nice, and not supporting the proprietary de facto standard would also be a bonus as long as the alternative works well enough.
