An alternative view on the subject of speed versus demand. One of the points of the article is that there isn't really much of a driver for higher speed computers. If your view is of the horsepower required to run Win95, Office95 applications at work; and basic run of the mill checkbook balancing and basic, modem speed limited websurfing kinds of things at home, Thomas Kurlak is probably not wrong. My view is a little different. On the consumer end, I see that we are at the cusp of a transformation in which different media - voice, video, imagery - that have information content - have the same kind of value to people as has text; and I submit that this new media environment is in fact, coming on stream faster than many of us might realize; and will continue to drive demand for microprocessors capable of handling that new media, bandwidth that can carry it, and storage that can hold it - and is doing that now. I've just installed Via Voice - a lower end continuous voice to text system - on my PC; and the long and short of it is that my juiced up 2 year old 133 can't keep up. Because it can't keep up, I can't use it to its fullest potential. To the point he made about video on the desktop and bandwidth as a driver..... How many of you have seen and heard some of the RealVideo, VDO, and other video streaming offerings on the Internet? With that technology today, bandwidth is the limiting factor for most of us; that basic old 100mhz system can play a 20kbs stream with good audio at around 6 or 7 frames per second in a window approximately 2 inches square with a little bandwidth left over for other things. Now, lets assume something a little different - oh 15 frames per second, and a half page display. Bandwidth required is up to 400kbs. I can encode a stream that that bandwidth using a twin 300 system today; and I can distribute it today, but that little old 100mhz system you have that does Win95 and Word doesn't have the gas to play the stream and do anything else. Who is providing that bandwidth? Cable companies. ADSL providors. DirecPC...... And, oh yes, corporate LAN users. IMO, this environment isn't as far down the road as Mr. Kurlak seems to be projecting. Who wants to provide continuous streaming video at 400kbs? Well, I do; and if I can, then I have an immediate potential worldwide audience of.... well a lot - for a whole lot less $ than it would take me using traditional methodologies..... The point is that in technology, capacity in advance of critical demand (shortage) always gets soaked up by people using things that take advantage of that capacity - often a lot faster than people would have forecast. Moreover, as one limit is overcome, increasing demand highlights other limits that when overcome highlight even other limits that get overcome.... and the cycle continues. On the producer side, there are also transformations occurring. Not that long ago, if I wanted to produce good quality graphics or if I wanted to be in a desktop publishing world, I was probably a Mac user. If I wanted to do dynamite graphics, CAD, 3D, animation, and the like, I was probably a Sun or SGI workstation user. The reason was that PCs didn't have the gas or the graphics capabilities that would support the requirement. Today, that just isn't true. I can buy a perfectly well equipped PC at the high end with the software I need to do most of these tasks for a lot less $ than I would pay if I wanted the platform to be one of those other brands. As a business person, if one of my engineers or graphic artists came to me with a requirement for a new workstation (assume, for example, it's a Mac), my question back to that person would be to explain why a PC wouldn't be able to do the same job. Increasingly, I think, users are going to fail at justifying the premium required by those other brands of workstations; and that at the end of the day, it will be a PC purchase. So. Is Mr. Kurlak wrong? On balance - it really doesn't matter! I've heard these kinds of comments for 30 years....... And, they have all been wrong. The only two questions, in my mind are (1) how fast capacity becomes inadequate, and (2) what's going to soak it up?
