What is perceived as "bloat" by the public is a combination of two factors: increased packaged data and the overhead required for proper structure. When I started it was considered pretentious to refer to an accomplished programmer as a "software engineer," whereas that is the minimum expected of any modern programmer; the senior programmers are "software architects." (I am neither, since it was only a sideline for me and I couldn't ride the rocket. I am still a "cowboy coder" who can knock out small applications and utilities without making a big mess of it.)
Did you ever see a DOS machine run on a network? It was ugly - surely you recall the "share" TSR to make files multi-accessible. There were email readers in the DOS days, but do you recall a web browser?
The good old days were good mainly because we know everything came out okay. However, in this case, we can go back. You can still load DOS on any modern Windows capable box. Go for it and let us know how it works out.

America, and indeed the world, pursue what is seen to be cutting edge technology just like codfish rush to bite an unbaited hook. Have things REALLY improved by quantum steps?
Software capabilities are not so greatly changed, and the chip technology - though greatly evolved - has developed solely to service the software which, indeed, has become bloated and glitchy.
You could run word processors, databases, spreadsheets, games, etc even on the old black and white Z80 machines. One company where I used to work ran the whole operation with two 10 megabyte harddrives and a Z80 network system.
Personal computers today do little that the old ones wouldn't do in some form or the other. Nor do they always do the job so terribly much quicker or better, although the microprocessors grunt along at multigigahertz speeds. We garbage mongers that feed the data into them are, oft as not, the limiting factor.
Mainframes had somewhat different requirements. They didnt have to cater to the executive gamer showoff computer-illiterate.

That quote from Billy-Bob has nothing to do with advances in design utilizing differing technologies. That only has to do with capacity - he was basing his opinion because of the current state of capacity. The technology hasnt changed in computers, but the capacity of devices has, such as faster CPUs (with increasing cache size), higher- capacity drives, more RAM, and so on.
Higher capacity is required because of bloated operating systems and the bloated software written by lazy programmers.
The basic design of the computer is still the same: to move 0's and 1's around the bus to peripherals, all controlled by various chipsets.

This reminds me of Bill Gates comment a few decades ago that no one should ever need more than 64k of RAM on his/her computer.
What you quote is incredibly short-sighted. It demonstrates a lack of willingness to do any kind of investigation of why fly-by-wire was considered. In short, these are the words not of an engineer, scientist, or technical person but a ninny, and a ninny tired of having more demanded of him for his labors, at that.
He's happy with the status quo. Others are not. He should get out of the business or certainly never enter it.

>Hi there. > [quoted text clipped - 16 lines] > >David This concern has been answered eloquently by a contributor to these newsgroups a few years ago. Sorry I can't name the author, but that person hit the nail squarely on the head with these words:
".........more importantly than that, you've got to have the insight and wisdom to know when something has been developed to the point where further development amounts to pointless engineering masturbation.
"The hydraulic brake system is a textbook model of development to perfection. So was the hydromechanical automatic transmission -- computerisation of the automatic transmission has taken away three-for-one in durability, dependability and cost of repair what little it has given us. We know how to make steering systems that work and essentially never give trouble. There is, therefore, no valid reason for steer-by-wire."

Hi there.
I have been looking at the new Honda Civic, it's pretty sweet, and the welds and everything are as nice as anything I have ever seen. I just have a question about the "Drive by wire" system that they are supposed to have.
What happens if the Engine dies on you? In my current car, my timing chip went once and the engine went out. I had enough steering control left, even without power steering, to pull my car over before it came to a stop. If the drive by wire system has no "real" or active connection, how can it work if the engine or electronics quit on you? Are there any backups built into the system in case any of that stuff happens? And what if your battery dies and you need to push the car? Can you turn the steering wheel to adjust your wheels when you push the car?
Much thanks, sorry to bother.
David
