Intel Looks to Billion-Transistor Processors

1THz processors are nice and all, but what about the necessary advancements in motherboard bus technology to match? I mean, you can have as fast a car you want, you get it to a track and flatten it's tires, it's not going to go very far. Personally, I would like to see a better partnership of chipset manufacturers and processor manufacturers to make sure that the rise of processor speeds is proportionate to the rise of chipset speeds.
Your post really demostrates that your are ignorant of what you're posting about.
AMD is not copying Intel's IP. If they were, Intel would be winning the suits against AMD, not losing them as they have been. AMD has reverse-engineered the x86 instruction set that has been around for quite some time, but implemented in silicon differently. The end result is greater performance, as evidenced by any benchmark you care to run. Like it or not, the fastest x86 processor on the planet right now, even according to Intel's own benchmark suite, is the Athlon XP 2000+.
And to further add insult to your injury, AMD doesn't stand for "American Micro Devices", it stands for Advanced Micro Devices. If you'd done the slightest bit of reading, researching, or thinking before you posted your previous comment, you'd know that.

We decided we wanted to do more with our computers. It's all very well to long for the days of very clever, small and fast programs but it's entirely another thing to create software which does all the things we have come to expect today while still keeping the software incredibly small and fast. It's even harder when you want to stay within a tight schedule and budget.
Lets look at something near and dear to our hearts, something that many of us here have contributed to and something that isn't affected by budgets or timelines (well, mostly) - the Linux kernel. The Linux kernel is undoubtably a very good piece of software development, arguably the best that's currently available and it has been created by a wide range of people many of who come from the days when RAM and CPU time was expensive. Despite this, the linux kernel is certainly not small, and it shouldn't be. It has a wide range of devices to support, it has to be able to handle multiple users simultaneously and it provides a bunch of services that previously would never have been provided in an OS, let alone in a kernel.
It could be argued that the Linux kernel is clever, and with my lack of knowledge of the kernel source I can't really comment. I think it is safe to assume that it's not as clever as it could be though - it doesn't use every trick in the book to reduce file size and increase efficiency because it's no longer small enough to make that kind of thing feasible. It's also modularised so that things can be loaded and unloaded as needed, there's extra code and overhead required to provide that. Finally, it supports a range of architectures now and is more portable. Going back to the old ways of doing things gives up all those benefits.
Finally, the linux kernel is not fast - it is comparably fast for all the things it does, but it is not as fast on a per-cycle basis as OS's were back when every cycle mattered. It does however provide more features (like loadable modules), more portability and a faster release schedule for fewer man hours.
So when you really sit down and think about it, while programs these days take up more RAM and CPU power there are a range of benefits that come from this. You should also note that comparatively the overall experience of using a computer has become radically faster then it previously used to. You may think that a program feels slow when you run it on a 3 year old machine, but what you fail to realise is that you've just gotten used to how much faster your new machine is. Having said that, some software is just plain crap, but so are some cars and bridges so the bad apples don't just come from software engineering.
Why should the processor have to predict the next mess of instructions, load them into a cache, find out it predicted incorrectly, dump the cache, find the correct location, load the instructions...
Incredibly poor chip design actually. This problem really only becomes significant when pipelines are made too long (such as in the P4). The pipelines are extended to make it possible to use a higher Mhz rating - though because of the extended pipeline and the problems caused by having to guess ahead so far the CPU doesn't actually function anywhere near as fast as the Mhz would indicate it should. This is why people talk about the Megahertz Myth - there's a ton of information on it around the web.
Why are processors marketed by their internal clock speed when they spend most of their time waiting for data?
Because consumers don't understand computers well enough to know this and Mhz has been used as a rating mechanism for so long (and previously it had been reasonably accurate). Marketers will jump at any opportunity to make their product sound better than the competition.
And above all, why does software suck so badly?
It doesn't. There is and always has been poorly written software but to say that all software sucks is unjustified. There are cars that break down due to manufacturing defects, bridges that collapse, constructions which go over time and budget and a myriad of failures from all types of engineering so of course not all software is perfect but it is improving whether or not you like the way it is improving is another matter.
