Go probably has a leg up on Clojure for reputation in production projects, considering Docker, K8s, Terraform, InfluxDB, and Geth are all written in Go. The biggest ones I can find written in Clojure are Puppet and CircleCI.

I migrated a team off of an aging enterprise application to the product that was rapidly gaining popularity in industry. I had some expertise and believed in it, I won't name products (and it wouldn't mean anything to HN anyway) but this was a painfully obvious change. We were the pilot project at the company, and went though 6 months of most users struggling. It was about 18 months after adoption that my boss told me he felt like the new product was both better and that the slow down had been worth it.
Life isn't long enough for too many of those experiments. Not everything takes that long. And the experiment could have failed. But the experience really put lots of decisions into perspective.
There's a saying that nobody uses technologies that their boss didn't learn in college. Factually inaccurate, quite astute in message.
Kotlin, for example, is a decent bit more complex than java is. It has a lot of new concepts to learn.
Yet, most Java devs can be productive with kotlin in a day or two. Even with the added concepts, it's not that different of a language.
The same is true of C and C++. A C dev could jump into C++ pretty quickly (even if they are just writing C with classes to start).
Your analogy is more like "Dig a hole, here's a shovel and here's a post hole digger". The familiar tool will likely go faster than the unfamiliar tool. And, as it happens, most devs are highly familiar with imperative programming styles, not so much functional programming paradigms.
It accelerates junior devs to production ready at the expense of everyone else.
It really feels like a language designed by people with utter contempt for those who actually write code.
Ultimately this is a disservice to those with any talent as it leads to a work environment where they are relegated forever to the lower ranks (unless they give up coding and move into management).
It's like hiring a new farmhand and saying, "here, dig two 3 foot holes, and we'll see what takes you longer, this shovel or an excavator you have no training or experience with," and then concluding the shovel is superior for all digging tasks from that point on.
