What are the downside of the Go programming language?

[kukac67]

The Go programming language obviously has many upsides, including its safety and simplicity. But every language has its downside.

So, besides potentially undesirable syntax, what downsides does Go have?

[Luuk]

• Go is still an experimental language subject to change. (I suppose this could be an advantage depending on how you look at it. For most it's probably a disadvantage.)
• Go's not very usable on Windows yet.
• The packages distributed with Go are pretty useful, but there are still some libraries you'll miss. Most notably a UI toolkit.
• There is no support for generics in Go, although there are many discussions around it.

"Go is only 3 years old. C is more than 40 years old. C++ more than 30. Perl 25. Ruby almost 20. Java is a relatively young language at 17, and C# quite young at 10 (or 12, depending on how you count it). And Java and C# had a lot of resources thrown at making them dominant, with Sun and Microsoft investing in all kinds of tools and libraries and getting people trained in them. Compared to that, 3 years is almost nothing. Google spends some money on developers for Go, but at nowhere near the scale of C# and Java. And 3 years isn't a lot of time for really prominent products to be written and released in Go."
