1. Go lang is strongly and statically typed. This means that a lot of mistakes that could potentially cause your code to blow up in production would be caught at compile time itself. Apart from this, if the language crosses a critical mass of adoption, someone will come up with an IDE that can possibly match Eclipse, IntelliJ, et al. Also, one of the principles behind the language’s design is to aid tooling which means that a lot of tools can possibly crop up which would help you to make your code more secure, performant etc.
2. Syntax of Go lang is not revolutionary. I consider this a virtue. I am strongly of the opinion that if a language has to gain mass adoption it’s syntax should be very close to the prevalent languages. Go lang does not deviate much from the Cish syntax but has subtle improvements which improves programmer productivity.
What makes Java a good programming language for the enterprise? Syntax of Java is very close to C which means that you could possibly train a lot of the computer science graduates out there to code in Java. Try Lisp with an average Joe programmer and you will know what I am talking about. With the people supply problem solved let us move on to other factors. Enterprises gravitate towards stability, security and viewing programmers as replaceable components of a machine. Java gives enough constructs to prevent a reasonably sane headed person from shooting themselves in the mouth. Static/strong typing, code analysis tools and IDEs go a long way in helping with this. Without tearing your hairs out, try working with a code base in a dynamic language which has been designed by an architect and then handed to a team for coding and then passed on to a testing team and then shifted over to an offshore team for maintenance. And to top it all, you do not have Eclipse or IntelliJ to help you with this mess.
Go lang has all the pluses of Java minus the verbosity. Of course it has a lot of other features which you can read about in the website.
