There's potentially a steep learning for Chisel especially if you're not coming from a Computer Science or programming language theory background.

It feels like Chisel is the result of functional programmers looking at the state of hardware design languages and being aghast at how archaic it is. Which is probably true but the value here will be helping experienced designers with no interest in learning CS theory build better chips faster. If Chisel can do that then it will win.

In my opinion the best languages have an extremely low barrier to entry. For example, C is very simple. The JavaScript development environment and tons of examples are readily available to everyone with a web browser. Python is cross-platform, has libraries for almost anything and relatively painless interoperability.
