As their github page says, based on https://ffmpegwasm.netlify.app ...

I'm guessing no one did GPU-optimizations? I saw a web app (not an ffmpeg transpilation) that went clever and used WebGL so it can access the GPU and use its parallel processing capabilities...

The algs for media codecs are typically in handwritten assembly in combination with C. Actual GPU hardware acceleration implements specific media algorithms in hardware and is not accessible from the browser. I'm not aware of any kind of gpu codec algs that work in browser.

They could use the WebCodec APIs to decode frames using the hardware, similar to how ffmpeg already supports VA-API for hardware decoding.

It’s nice if you have a modern computer, but I wonder what happens when the client has a very old computer or a “Chromebook”.

Will the experience for those low end computers be degraded?

It’s been awhile since I actually used ffmeg directly but I do recall trying to transcode some video to a different format and it took some time on a 2015 MacBook (not a MBP, like a thinner version of the MBA, lol)
