Personally I think this is going to change soon depending on what 
options are available.  The amount of time and money that 
companies, especially companies using Java and AWS, are putting 
in to saving money with Nomad or Kubernetics on the promise of 
having more services per server is quite high.  However, these 
JVM based services run in maybe 1-2GB of RAM at the minimum, so 
they get maybe 4 services per box.

A microservice built using D and vibe.d could easily perform the 
same work using less CPU and maybe only 500MB of RAM.  The scale 
of improvement is roughly the same as what you would get by 
moving to containerization.

If D has the proper libraries and integrations available with the 
tools that are commonly used, it could easily break through and 
become the serious language to use for the competitive business 
of the future.

But libraries and integrations will make or break that.  It's not 
just Java you're up against, it's all the libraries like 
SpringBoot and all the integrations with AWS systems like SQS, 
SNS, Kinesis, MySQL, PostGREs, Redis, etc.

My hope is that D will be part of that future and I'm trying to 
add libraries as time permits.
