A lot more ads. Maybe 3D or holographic or something. The ads of today have overcome the tech advances, essentially rendering the net less efficient than it was 15 years ago. This new development may send us back to the 19th century.

Ultrafast wi-fi, which is 100 times quicker than today’s mobile networks is on the horizon, after scientists proved they could send complex data using high-frequency radiation.

The researchers sent video signals using terahertz, rather than traditional microwaves, at speeds of 50 gigabytes per second. Most wireless networks only operate at top speeds of 500 megabytes a second.

The breakthrough could lead to high-speed streaming on the go.

Or more ads. Maybe cancer.
