And wasn't that computing model all the range 40 years ago, with "big iron" (less powerful than my phone now) mainframes that lived far away and dumb terminals (essentially a keyboard and a screen with very little processing happening locally)?
Are we saying computing is so hard that people can't be trusted with a real computer? Everything needs to be on someone else's computer and you are only allowed to have a locked down browser locally?
I don't get this everything old is new again trend. And how enthusiastic today's kids are about their grandfather's computing model.
Portability (and not just between architectures--between operating systems as well).
> and now treating JavaScript as CPU op codes?
Web Assembly does not treat JavaScript as "CPU op codes".
I'll add that I think your confused about what I am saying. In the JavaScript world, the single page app is really just a pure client side app, no different than an app dedicated to Windows like Word. The difference is that it targets web standards for building applications, in a sense the browser is the operating system and application development environment that the OS used to provide.
The key is that it's a standard, and should work the same across platforms. The fact that it's on the web is just a delivery platform for the software.
Webassembly will bring the performance of these browser based applications to be on par with any native application. It's the write once run everywhere development that we've all wanted since the promise that Java made.
I do think that there is a benefit to this model over Java, which is that it's more flexible than Java was in allowing for design choice, and many more languages (in large part thanks to the LLVM).
The browser should be a rendering engine, which is a pure sandbox, for client side applications. The client side applications will have access to standard local dbs, standard Dom and CSS renderers and standard method of running code through webassembly.
Webassembly with DOM access is IMO the final piece to do this. And then all OS device access will be done through this sandbox environment where there can be highly controlled access to things like mounted disks, etc. In this utopian future, all developers will be able to target any browser/OS with identical code and never have compatability issues.
