I'm not trying to pick on it. But those languages are significantly harder to develop for. Go/Swift are trying to be general improvements that maintain and improve upon developer productivity while achieving great performance and efficient memory utilization (which if you look at the paper is one area Java is not necessarily great at).

Makes sense. It didn't come across that way since you mentioned the energy savings and then immediately mentioned those alternatives. Interestingly though, while Java used a lot of memory, the energy expenditure for DRAM is still one of the lowest for Java. And they found little correlation between memory usage and DRAM energy in general. I wonder why that is.

  Yeah they only looked at peak memory. They noted it would be more useful to look at continuous memory usage in future research. Also take note that the scale of the graphs is different. E.g. Figures 5 & 6 makes it look like Java energy is super low when it's really just similar to the compiled languages.[1] [1] http://greenlab.di.uminho.pt/wp-content/uploads/2017/10/sleFinal.pdf http://greenlab.di.uminho.pt/wp-content/uploads/2017/10/sleF...

Ada is not particularly difficult. It does suffer from a lack of tooling compared to some languages. It's a large language with many ways to do things and some dark corners. The same never stopped C++, Ruby, Perl, nor in its day PL/1. If you can learn C++ or Java then Ada is largely syntax changes, not wildly different semantics. If you know Pascal it's basically a huge extension with support for features like concurrency and pointers never standardized into Modula 2 or Pascal.

I have written server's in Kotlin, that run on the JVM and thus are practically the same. IMO I am far more productive then using Swift, plus you have access to a huge legacy of stable, well thought out, and documented libraries.
