Ask HN: What do you predict for front end web development for the next 5 years?

A big part of web development is picking the right trends to be on.

A large, active ecosystem allows you to be more productive. Instead of rolling you own, you get to use a well-tested library.

Instead of guessing the best approach yourself, you get to read blog posts about people who have learned what not to do.

If you are passionate about programming, you like to learn the insides out of a programming language and framework. But all the while, in the back of your head you know that all this may be be wasted time one day when the ecosystem shifts out from under you.

So my question is, what are your predictions for web development over the next 5 years and why? What will we be talking about in 2018 and what about in 2020?

Examples:

- Do you see WebAssembly coming to fruition?

- Will a new language emerge?

- How will Angular 2 / React / Ember play out?

- Will we see a React "Framework" come to prominence.

- Will usage of Babel taper off as browsers standardize ES6/7 and SystemJS.

- Will webpack still be the go to packaging solution?

- Will NPM maintain itself as the dominant package manager?

The reason for asking this question is to avoid wasting time becoming an expert and contributing to a tool/language/etc. that won't be around in 2-5 years time.
