At QConLondon next week, I'm hosting the "Modern Native Langauges" track which will have presentations on Rust, Go, Pony and Swift:

The presentations are being recorded and will be published at http://www.infoq.com/qcon-london-2016/ over the next few months (you can see last year's conference content at http://www.infoq.com/qcon-london-2015/ if you're interested).
It's certainly a great time to be a developer with an interest in languages!
