It has, but it wasn't adopted by the pragmatists in that time.

It's hard to tell if the early adopters adopted it either

- It doesn't show up at all in the 2023 stack overflow survey (nor in the previous two years) - https://survey.stackoverflow.co/2023/#technology-most-popula...

- It doesn't show up in questions asked on Stackoverflow since 2008 - https://insights.stackoverflow.com/trends?tags=kotlin%2Crust...

- Nor on Google insights - https://trends.google.com/trends/explore?date=2012-07-31%202...

But maybe there is a different data set that shows early adopters adopting D. But for me, I would say a language has been adopted by early adopters when it reaches 1% of all developers in a reasonably large survey. Given that, it's entirely fair for a company making a language decision now to ask if D will still be around in 10 years.
