I've frequently described Go as a very, very good 1990s language. Going through the process of maturity takes time. You can't have a "very, very good" 2020s language right now, because at the frontier we're still feeling our way through the issues.

(Remember, whatever you're about to hit reply with and try to contradict me about it being a totally smooth and polished 2020s language that's already here is also an assertion that your example basically has no room for improvement and will not improve in the next 10-20 years. Consider your options carefully before you go too "language partisan" here.)

I believe probably >75% of the hatred Go engenders is from people afraid that Go's success will erase or invalidate the 2010s/2020s languages they prefer, because otherwise, the solution to most of these people's hate/anxiety would be to just ignore Go. To which I can say to those people, you can stop worrying. It won't. And if you stay in the industry long enough, maybe someday you'll get to use the really good and polished 2010s or 2020s language. No idea what it'll be called. And you can similarly assuage the fears of the day that this new language will erase all the benefits of the 2040s languages in development at the time.

But for "opinionated" to really work, I think you intrinsically need to have years of experience to make the right calls. There's no realistic chance that we could have gone straight to the "correct" VPN choice in one shot. Too many variables, too many dimensions, too much to learn and know about the security. It's just not possible. We collectively need the decades.
