Counter-opinion: industry simply has no plausible alternative to Verilog/SystemVerilog and succeeds in producing chips only in spite of the language's glaring flaws.

I worked for several years at a world class company verifying CPU designs. Even into the late 2010s, designers were afraid to use basic features like structs because who knows what tool might not support it correctly. They emulated structures using piles of defines that set all the bit offsets. I wouldn't know how to begin to estimate the amount of senseless work that this led to during debugging. The lack of any type safety was appalling. If you were lucky, you could catch gross type confusion by having a linting tool notice a size mismatch. These tools found hundreds of real errors that should never have compiled in the first place. I could go on and on...

But there's no escaping it. There are so many amazing tools built around it. The vendors love the moat the complexity gives them. The IP developers have huge investments in legacy code bases. Compatibility is worth too much.

The industry is extremely conservative. Costs of designing and taping out a modern chip range from $100M to $1B; these are the type of costs that will kill most companies if it goes wrong and very few companies can afford to have it go wrong more than once.

Tried and true approaches, small incremental developments are the only way things get done in this space. And the technological moat has many sources, not just Verilog etc. Process technology is continuously evolving and tools need to adapt to all the new physical rules and constraints. What gates are most efficient depends on the problem and the process and even by what the team means by efficient (least power? least energy? most mips/sec? least time to solve a problem? ...)

Everyone loves to complain about the tools though, that is universal. They'll just never adopt a new tool that hasn't survived the test of time and had enough successful designs "by someone else" that it doesn't make them nervous about being the first.
