It seems much more likely that we hit a threshold after which it won't make any difference if you have 6 or 7 billion gigahertz on your processor cause it'll be so fucking good it makes no difference anyway. Not to mention, things keep getting smaller, but a cellphone can't be the size of a finger nail so there are certain physical limitations. Both because it would be inoperable, and because even though microchips are totally awesome, they too have physical limitations.
Technically there's no point in creating processors that are faster than ~3ghz.
A pentium 4 processor released 5-6 years ago had 3,8ghz. These days most mainstream processors are between 2 and 2.8ghz and are at least 5 times faster and more efficient.
I wonder if we'll ever hit a level at which we'll start going backwards if you know what I mean.
That we will reach a level that will be hard to keep on for a longer time. It would be interesting.
Bare in mind that human brain has evolved so much that most awesome discoveries were made over the last 2000 years and think about the fact that the majority of the most awesome ones were made during the last 100 years. 30-few years ago the idea of a personal computer was found. Development of new technologies is going faster and faster.
I don't even have any idea what will our world look like within 20 years but I bet it'll be totally different. Predicting 2100 is crazy, then how can we predict what will happen in 5 billion years?
However the odds are that earth will be destroyed by a huge asteroid way earlier and the most sad thing is that it can happen basically at any time, any second and there would most probably be no warnings before unless that object would be really big and slow.
Actually it's almost unbelievable that we're still alive since the likelihood of our planet being destroyed by it is really high.
