It is the year 2020: why should I use / learn D?

By the way, you keep mentioning that you use D for your own 
internal stuff, and as far as I can see a lot of companies that 
use D do the same. They have their own in-house ecosystem, and 
that's fine. Of course, for this kind of usage D might be OK 
(apart from the facepalm flaws it still has) - or any language 
for that matter.

However, a lot of IT companies (small, medium and big) also have 
to adapt to the market in terms of third party products like 
Android and iOS and other technologies (including those that do 
not yet exist). Once that's the case, D is one of the worst 
choices possible. Everything takes years, anything that is not 
directly related to (some specific features of) the language is 
treated as lowest priority, and a small or medium sized company 
may not be able "to roll its own" all the time, especially if 
everything is still raw and has a lot of loose ends as in the 
case of D. And you know what, customers don't care about your 
problems. They simply go somewhere else, if you can't deliver. So 
what you need is a language that provides adaptability out of the 
box. This is why a lot of new languages invest in exactly this 
and try to open as many "ports" as possible, to make the language 
as useful as possible. Only in this way they will be adopted by 
users. Your "cosmos" is D and your own company. But most other 
people have to cater for third party software as well and adapt 
to an ever changing market. I think this is a fact you're not 
really aware of. You can talk all you like about the cosmos and 
the universe, but all you see are your own needs for which D 
might be fine. But reality is different for other people.
