Look at Chisel. I agree that C/C++ is the wrong abstraction but that's because using a HDL is more like meta programming in a declarative markup language that needs to be embedded in a higher level language for automation and verification than to compile imperative operations into silicon.

Lookup tables are the big thing that break CPU and GPU programs since at relatively small sizes you'll hit the memory wall. A lot of algorithms like media codecs (audio, video) and pretrained neural nets are trivial to design with HLS and have a major performance advantage over using a CPU or GPU.

Add in the fact that CPUs and GPUs are expensive as fuck, in short supply, demand high power, while FPGAs are pretty cheap and efficient since they don't do much you're going to find a lot of designs that call for them over a beefy and expensive chip.

That said, arm and risc V cores are dirt cheap. If your algorithm isn't hitting the memory wall it probably isn't going to be faster via HLS.

so, almost universally derided and a major source of division in the linux ecosystem that make it unsuitable for general consumer use?
