The internet is very slow

There is an area called the deep web, which search engines have not found as yet

The deep web is getting bigger

people are trying to make search engines more intelligent to cover more up of the deep web

connecting to the internet will increase

The online and offline will blur together

sometimes when searching somethings it takes avery long time to load

This is because the connection speed is too slow and the problem mainly lies at the last mile to your home

there are a lot of devices that can connect to the internet

Now it is possible to blend what you are seeing with extra information

this is called augmented reality or AR for short
