This is nothing from the Sunnah or the Quran, just my own useless opinions. Of course it will end with the final major signs (the last one being the sun rising from the west). But in the mean time, what will happen (other than the prophetic signs)?
Well my guess is technology will self destruct. Seems far fetched, however things cannot always be improving. Look at technology since the 1800s, it has always been on the rise.
The first thing we learn is: what goes up must come down. I can't say I know how it will end, we will have to wait and see..
