Not sure why the downvotes. iFrames does need a revolution.

iFrame, yet how clunky, ghastly to work with; is what driving the web. Gmail, Facebook all use them in their apps.

It's a feature that if deprecated would cause a broken World Wide Web; as if it isn't broken already... One could say.

Reaching into my pessimistic, dark side - if we transition to most processing being done in the cloud, such that we eventually give up powerful devices for simpler cloud AI terminals in general, I could see the concept of the "client" side also living in the cloud, similar to cloud gaming. In that case, the internet would be more like cable where you just accept the commercials because you can also watch ninja turtles in between them.
