      To a first approximation, in 2020 image codecs would parse and entropy decode in Rust, throw the resulting bits on GPU, and do everything else there.

      Should we be worried about memory safety of GPU code too though? I haven't done enough to get a good feel for it.

      Yes, but the GPU memory model is so much simpler that it's easier to attain. (For example, WebGL is memory safe already--it has to be, because it's exposed to content.)

      But it doesn't because the hardware doesn't. We just look the other way around that. Browsers should not be touching GPU at all. Only apps dealing only with data created by their user or other highly trusted parties should have GPU access.

      Strong disagree, as someone who has dealt with the complaints about power usage from not using the GPU enough.

          I will trade power usage for user safety any day. But we shouldn't have to. Should just nuke whatever silly site-design gimmicks are wasting power and present a simple accessible view of the page.
