Limitations and the future of HTML + JavaScript for web applications

Question

I'm a non-web programmer, but now I'm more interested in web technology.

I know that HTML and JavaScript today are fundamental technologies for web applications, but it also seems that in fact they were not created strictly for this. (HTML was created for web pages, JavaScript to make them a bit dynamic). Does it have any significant negative impact on how modern web applications are created today? What are the limitations?

Do you predict the emergence of new technology in 5-10 years to replace HTML + JavaScript? If so, what will it be?
