I am looking forward to how powerful processors will be ten years from now. I spend a lot of time rendering 3D graphics on my home computers, but there are some types of animations I tend to avoid simply because I know they will take years to render. Hopefully one day, even these will be possible in just a few minutes on home computers.

Ten years from now we'll be seeing the first consumer quantum computers, possibly with light-based processors. Moore's Law may or may not apply, since it's already started to fail -- two years to doubling instead of eighteen months. No telling what effect new paradigms and technologies will have on it.

batfan1939 In ten years there will be things for consumers that we don't even know how to build in a lab yet? I don't think so. It's not even clear optical computers provide any advantage over electronic computers. Quantum computers will probably always be some kind of coprocessor in general-purpose computers.

The whole testing cpu's bit is pretty fun. They are just so complicated that full simulations are way too slow. And by that I mean they run at a couple hertz, compare that to the gigahertz the actual processor runs at. And even partial simulations are only somewhat better although there are specialized and horribly expensive machines that kind of help. And then there are those bugs that are way too obscure to ever be found by humans and just randomly testing stuff is really slow... Point is, the first second after turning a cpu on might do more testing than the entire development up till then. I have some serious respect for the people that somehow manage to make them work almost all the time.

I know Intel has had a few silicon bugs. Never heard of ARM having them. I know there are device specific silicon limitations/errata (specifically in the microcontroller space) for ARM, but likely more due to manufacturer faults than CPU design. So how many design bugs does ARM have/had?
@stensoft

+leppie The mainstream-discussed Intel's bugs were always in microcode (Pentium FDIV, Halt and Catch Fire, Skylake), not the chips themselves. ARM chips don't use microcode, they are therefore much simpler and easier to test. (This has a lot to do with that Intel uses CISC instructions while ARM uses RISC. Intel's instructions are designed to be easy to use while ARM's to be easy to implement. Since almost nobody programmes in assembly anymore, guess who's better for today's world.) On the other hand, there were a few bugs during the years as well. If you can get hold of ARM documentation, look for errata.

I've been programming since I was 8 and even though it's not related to my occupation or studies, I do it on a daily basis as a hobby that has brought me a lot of joy.

Nope. The future is looking to be FPGA-ASIC hybrids with with home computers turning into a terminal on a mainframe. I wish it was otherwise. I love open source hardware, but look up the Xilinx Amazon partnership that was recently announced. Then ask why Intel bought out Altera. The end of Moore's Law will result in the expansion of FPGAs. FPGAs are capable of running a local user interface with remote software faster than a consumer grade system with local storage. Why the shift? Proprietary software security. You won't have access to the complete software on a terminal based system. The future will be the 1960's mainframe computer version 2.0... if open source projects like the linux kernal don't take most of the market share first. -Jake

So Jem Davies and Steve Furber disagree on the origins of the phrase "tape out". In another computerphile video Furber says that "tape out" comes from writing the design schematic to tape that'll then be shipped to the foundry to make masks.. Given that Furber was there and doing it, I'm going to put my bet on him.. (Which video? Dunno, I've watched a few, and there isn't a transcripts to search, and I'm too lazy to find out which one.)

A question about people like these architects of arm. what kind of education do they need to have the knowledge required for such job? I know that it's probably not business administration, but other than that, not much. I'm just asking out of curiousity because the things he talks about seem to include both hardware and software and other stuff.

+ahenryb1 Depends on which side of the pond you're on. In American English, "ARM" is a company, and thus a singular entity, so properly conjugating "do not" yields "doesn't" instead of "don't". In British, "ARM" might be plural, because British English is different, in which case "don't" would be correct.

"ARM does not fabricate chips" or "ARM only designs chips" would have been fine titles too. In american english, the phrase "ARM don't make computer chips" is what we call "Hickish", it sounds as if its in a southern vernacular, much like "I ain't gonna eat them chips"
