My brother forwarded this to me. I'm a little skeptical as to it's
authenticity since the transcript lists Stroustrup's name as "Structure"
in the first half of the interview (even I'm not sure how it's spelled,
though). But *if* it is real it's a rather interesting article. Certainly
keeps in line with what I've heard of Stroustrup, which is that he never
really liked C++.
Read it with a grain of salt. If anyone can verify this as being
authentic, I'd love to hear about it.

> Naturally, the editors thought he would be giving a retrospective view of
> seven years of object-oriented design, using the language he created.
>
> By the end of the interview, the interviewer got more than he had bargained
> for and, subsequently, the editor decided to suppress its contents, 'for the
> good of the industry' but, as with many of these things, there was a leak.
>
> Here is a complete transcript of what was said, unedited, and unrehearsed,
> so it isn't as neat as planned interviews.

> Interviewer: Well, it's been a few years since you changed the world of
> software design, how does it feel, looking back?
>
> Structure: Actually, I was thinking about those days, just before you
> arrived. Do you remember? Everyone was writing 'C' and, the trouble was,
> they were pretty damn good at it. Universities got pretty good at teaching
> it, too. They were turning out competent - I stress the word 'competent' -
> graduates at a phenomenal rate. That's what caused the problem.
>
> Interviewer: Problem?
>
> Structure: Yes, problem. Remember when everyone wrote Cobol?
>
> Interviewer: Of course, I did too
>
> Structure: Well, in the beginning, these guys were like demi-gods. Their
> salaries were high, and they were treated like royalty.
>
> Interviewer: Those were the days, eh?
>
> Structure: Right. So what happened? IBM got sick of it, and invested
> millions in training programmers, till they were a dime a dozen.
>
> Interviewer: That's why I got out. Salaries dropped within a year, to the
> point where being a journalist actually paid better.
>
> Structure: Exactly. Well, the same happened with 'C' programmers.
>
> Interviewer: I see, but what's the point?
>
> Structure: Well, one day, when I was sitting in my office, I thought of
> this little scheme, which would redress the balance a little. I thought 'I
> wonder what would happen, if there were a language so complicated, so
> difficult to learn, that nobody would ever be able to swamp the market with
> programmers? Actually, I got some of the ideas from X10, you know, X
> windows. That was such a bitch of a graphics system, that it only just ran
> on those Sun 3/60 things. They had all the ingredients for what I wanted. A
> really ridiculously complex syntax, obscure functions, and pseudo-OO
> structure. Even now, nobody writes raw X-windows code. Motif is the only way
> to go if you want to retain your sanity.
>
> Interviewer: You're kidding...?
>
> Structure: Not a bit of it. In fact, there was another problem. Unix was
> written in 'C', which meant that any 'C' programmer could very easily become
> a systems programmer. Remember what a mainframe systems programmer used to
> earn?
>
> Interviewer: You bet I do, that's what I used to do.
>
> Structure: OK, so this new language had to divorce itself from Unix, by
> hiding all the system calls that bound the two together so nicely. This
> would enable guys who only knew about DOS to earn a decent living too.
>
> Interviewer: I don't believe you said that...
>
> Structure: Well, it's been long enough, now, and I believe most people
> have figured out for themselves that C++ is a waste of time but, I must say,
> it's taken them a lot longer than I thought it would.
>
> Interviewer: So how exactly did you do it?
>
> Structure: It was only supposed to be a joke, I never thought people would
> take the book seriously. Anyone with half a brain can see that
> object-oriented programming is counter-intuitive, illogical and
> inefficient.
>
> Interviewer: What?
>
> Structure: And as for 're-useable code' - when did you ever hear of a
> company re-using its code?
>
> Interviewer: Well, never, actually, but...
>
> Structure: There you are then. Mind you, a few tried, in the early days.
> There was this Oregon company - Mentor Graphics, I think they were called -
> really caught a cold trying to rewrite everything in C++ in about '90 or
> '91. I felt sorry for them really, but I thought people would learn from
> their mistakes.
>
> Interviewer: Obviously, they didn't?
>
> Structure: Not in the slightest. Trouble is, most companies hush-up all
> their major blunders, and explaining a $30 million loss to the shareholders
> would have been difficult. Give them their due, though, they made it work in
> the end.
>
> Interviewer: They did? Well, there you are then, it proves O-O works.
>
> Structure: Well, almost. The executable was so huge, it took five minutes
> to load, on an HP workstation, with 128MB of RAM. Then it ran like treacle.
> Actually, I thought this would be a major stumbling-block, and I'd get found
> out within a week, but nobody cared. Sun and HP were only too glad to sell
> enormously powerful boxes, with huge resources just to run trivial programs.
> You know, when we had our first C++ compiler, at AT&T, I compiled 'Hello
> World', and couldn't believe the size of the executable. 2.1MB
>
> Interviewer: What? Well, compilers have come a long way, since then.
>
> Structure: They have? Try it on the latest version of g++ - you won't get
> much change out of half a megabyte. Also, there are several quite recent
> examples for you, from all over the world. British Telecom had a major
> disaster on their hands but, luckily, managed to scrap the whole thing and
> start again. They were luckier than Australian Telecom. Now I hear that
> Siemens is building a dinosaur, and getting more and more worried as the
> size of the hardware gets bigger, to accommodate the executables. Isn't
> multiple inheritance a joy?
>
> Interviewer: Yes, but C++ is basically a sound language.
>
> Structure: You really believe that, don't you? Have you ever sat down and
> worked on a C++ project? Here's what happens: First, I've put in enough
> pitfalls to make sure that only the most trivial projects will work first
> time. Take operator overloading. At the end of the project, almost every
> module has it, usually, because guys feel they really should do it, as it
> was in their training course. The same operator then means something totally
> different in every module. Try pulling that lot together, when you have a
> hundred or so modules. And as for data hiding. God, I sometimes can't help
> laughing when I hear about the problems companies have making their modules
> talk to each other. I think the word 'synergistic' was specially invented to
> twist the knife in a project manager's ribs.
>
> Interviewer: I have to say, I'm beginning to be quite appalled at all this.
> You say you did it to raise programmers' salaries? That's obscene.
>
> Structure: Not really. Everyone has a choice. I didn't expect the thing to
> get so much out of hand. Anyway, I basically succeeded. C++ is dying off
> now, but programmers still get high salaries - especially those poor devils
> who have to maintain all this crap. You do realize, it's impossible to
> maintain a large C++ software module if you didn't actually write it?
>
> Interviewer: How come?
>
> Structure: You are out of touch, aren't you? Remember the typedef?
>
> Interviewer: Yes, of course.
>
> Structure: Remember how long it took to grope through the header files
> only to find that 'RoofRaised' was a double precision number? Well, imagine
> how long it takes to find all the implicit typedefs in all the Classes in a
> major project.
>
> Interviewer: So how do you reckon you've succeeded?
>
> Structure: Remember the length of the average-sized 'C' project? About 6
> months. Not nearly long enough for a guy with a wife and kids to earn enough
> to have a decent standard of living. Take the same project, design it in C++
> and what do you get? I'll tell you. One to two years. Isn't that great?
> All that job security, just through one mistake of judgment. And another
> thing. The universities haven't been teaching 'C' for such a long time,
> there's now a shortage of decent 'C' programmers. Especially those who know
> anything about Unix systems programming. How many guys would know what to do
> with 'malloc', when they've used 'new' all these years - and never bothered
> to check the return code. In fact, most C++ programmers throw away their
> return codes. Whatever happened to good ol' '-1'? At least you knew you had
> an error, without bogging the thing down in all that 'throw' 'catch' 'try'
> stuff.
>
> Interviewer: But, surely, inheritance does save a lot of time?
>
> Stroustrup: Does it? Have you ever noticed the difference between a 'C'
> project plan, and a C++ project plan? The planning stage for a C++ project
> is three times as long. Precisely to make sure that everything which should
> be inherited is, and what shouldn't isn't. Then, they still get it wrong.
> Whoever heard of memory leaks in a 'C' program? Now finding them is a major
> industry. Most companies give up, and send the product out, knowing it leaks
> like a sieve, simply to avoid the expense of tracking them all down.
>
> Interviewer: There are tools...
>
> Stroustrup: Most of which were written in C++.
>
> Interviewer: If we publish this, you'll probably get lynched, you do
> realise that?
>
> Stroustrup: I doubt it. As I said, C++ is way past its peak now, and no
> company in its right mind would start a C++ project without a pilot trial.
> That should convince them that it's the road to disaster. If not, they
> deserve all they get. You know, I tried to convince Dennis Ritchie to
> rewrite Unix in C++.
>
> Interviewer: Oh my God. What did he say?
>
> Stroustrup: Well, luckily, he has a good sense of humor. I think both he
> and Brian figured out what I was doing, in the early days, but never let on.
> He said he'd help me write a C++ version of DOS, if I was interested.
>
> Interviewer: Were you?
>
> Stroustrup: Actually, I did write DOS in C++, I'll give you a demo when
> we're through. I have it running on a Sparc 20 in the computer room. Goes
> like a rocket on 4 CPU's, and only takes up 70 megs of disk.
>
> Interviewer: What's it like on a PC?
>
> Stroustrup: Now you're kidding. Haven't you ever seen Windows '95? I think
> of that as my biggest success. Nearly blew the game before I was ready,
> though.
>
> Interviewer: You know, that idea of a Unix++ has really got me thinking.
> Somewhere out there, there's a guy going to try it.
>
> Stroustrup: Not after they read this interview.
>
> Interviewer: I'm sorry, but I don't see us being able to publish any of
> this.
>
> Stroustrup: But it's the story of the century. I only want to be remembered
> by my fellow programmers, for what I've done for them. You know how much a
> C++ guy can get these days?
>
> Interviewer: Last I heard, a really top guy is worth $70 - $80 an hour.
>
> Stroustrup: See? And I bet he earns it. Keeping track of all the gotchas I
> put into C++ is no easy job. And, as I said before, every C++ programmer
> feels bound by some mystic promise to use every damn element of the language
> on every project. Actually, that really annoys me sometimes, even though it
> serves my original purpose. I almost like the language after all this time.
>
> Interviewer: You mean you didn't before?
>
> Stroustrup: Hated it. It even looks clumsy, don't you agree? But when the
> book royalties started to come in... well, you get the picture.
>
> Interviewer: Just a minute. What about references? You must admit, you
> improved on 'C' pointers.
>
> Stroustrup: Hmm. I've always wondered about that. Originally, I thought I
> had. Then, one day I was discussing this with a guy who'd written C++ from
> the beginning. He said he could never remember whether his variables were
> referenced or dereferenced, so he always used pointers. He said the little
> asterisk always reminded him.
>
> Interviewer: Well, at this point, I usually say 'thank you very much' but
> it hardly seems adequate.
>
> Stroustrup: Promise me you'll publish this. My conscience is getting the
> better of me these days.
>
> Interviewer: I'll let you know, but I think I know what my editor will
> say.
>
> Stroustrup: Who'd believe it anyway? Although, can you send me a copy of
> that tape?
>
> Interviewer: I can do that.
