Removing Software Complexity
t482 writes "Charles Simonyi (ex Xerox Parc & Microsoft ) says that Software "has become a field where we focus on incremental improvements in processes. That course is futile, because it can never solve the problem of human imperfection."
Even as software collapses under the weight of its own complexity, we've barely begun to exploit its potential to solve problems. The challenge, Simonyi believes, is to find a way to write programs that both programmers and users can actually read and comprehend. Simonyi's solution? To create programming tools that are so simple and powerful that the software nearly writes itself.
"Software should be as easy to edit as a PowerPoint presentation," Simonyi asserts."
Little known fact: This is the same Simonyi who invented hungarian notation.

I write a blog now, you should be afraid.
Will write the programming tools? Seems to me Simonyi's not talking about a replacement for modern programming, but an incremental advancement over say AppleScript or Hypercard. More powerful userland tools will not completely replace programming: someone will need to write the components. Or is he thinking that all the components will be in the OS, and thus third party programmers could be eliminated and the OS vendor and the user would be the only parts of the transaction?
There's a whole raft of tools out there that put this philosophy into action - witness MS Access, VB etc. Even an Excel spreadsheet can be viewed as a 'programming environment' really.
There are 2 kinds of problems that programmers solve - technical problems and business problems. The technical problems can be abstracted by tools like the above, but the business problems remain.
Techniques such as Object Oriented design, abstraction, etc etc are just as useful for solving these kinds of problems as they are, for example, when writing a new web browser.
It's difficult to see how a groovy GUI can hide or solve these problems. You're still going to need a certain set of skils to guide the development and architecture of any nontrivial system.
I'm sure we've all see complex websites that have been put together by naive users of Frontpage - bloated HTML, endless redundancy (cut-n-paste) and a hideous task for someone else (with a similar skill level) to pick up and modify. It's hard to see how you can prevent these kind of problems when you go down the "everyone can use it" path.
"The problem is programmers are not known for their empathy for users"
Oh, I don't know...my customers and I often share amusing stories of stuff that's Blue screened just before you meant to save it. If you mean that some Programmers consider themselves godlike because of years of hubris and the certain knowledge that you couldn't be found out if you cloaked as much as you could in jargon, then you might have a point.
The customer knows what they want, and they'll express it to you in their terms; you have to translate their ideas into something workable, which can be a ballache, but if you've started from a position of billable hours rather than a fixed cost, you're already ahead of the game simply because you can work on milestones rather than having to constantly rehash.
The idea of having a high-level language that 'anyone' can use has largely already happened with HTML. As a result we have some outrageously bad HTML out there because of the complete lack of understanding of abstraction. Put simply, Decamino wouldn't look through Galileo's telescope because he _knew_ that Galileo is wrong; the paradigm that allowed for the earth to move out of the center of the universe hadn't yet come to pass.
Although OO is currently viewed with some suspicion because it may not be the best way to do _everything_, everyone involved in commercial programming has at least started to view things in the terms of objects; that concept may take a while to filter down to a public that thinks animated cursors on the web are the dog's back wheels, or seem surprised when you have to keep AV software updated.
Oddly Draconis
Too cynical to live, too stubborn to die.
I'm not saying things like API obfuscation or similar. I mean people don't generally think logically. Computers don't think emotionally. The average person has no idea about algorithms, or why you may want an O(lg(n)) algorithm in preference to an O(n^2) algorithm.
For these things, professional programmers will still be required.
I can't say that I don't give a fuck. I've just run out of fuck to give.
I think it's great for them to pursue tools that make it easier for non-programmers to do more useful things for themselves.
I'm not too concerned that this will replace the current type of programming, though. The biggest problem is that the real-world problem being solved is almost always more complicated than the domain experts themselves realize.
When I sit down with a client domain expert to write a program for them, they are invariably surprised by what I uncover. I gradually tease out a huge variety of scenarios that they've never thought through or decisions that they make on the basis of "experience" whose rules they can't possibly express explicitly, comprehensively, unambiguously, and without contradiction -- on their own.
It just doesn't matter how easy it is to explain the rules to a computer if you don't have the skill that experienced programmers have: to completely specify the problem. Fully explaining how to solve a problem to something other than another intelligent and experienced human is harder than most non-programmers realize. (Of course Simonyi knows this, but the journalists who cover his work probably don't.)
"Those who have never entered upon scientific pursuits know not a tithe of the poetry by which they are surrounded."
No, VB and Access made it possible for untrained people (and naive managers) to THINK (quite incorrectly) that they could write software and DB apps.
Exactly.
There is no silver bullet for making software easy, and this has been known for decades.
Cobol, for instance, was supposed to be English-like, and hence understandable and programmable by non-programmers. Other English-like programming languages have made the same claim. Wrong every time on all counts.
The problem is that specifying arbitrary algorithms requires extreme precision, unambiguity, and tedious detail far beyond anything the average person is even interested in attempting, let alone capable of. It doesn't particularly matter which language or tool is offered, what matters most is the person's abilities (and willingness!) to be excruciatingly detailed and logical and patient.
This has been studied to death, but hope springs eternal...
Another kind of lack of silver bullet are declarative languages...it's vastly easier to declare what is needed than it is to specify procedurally how to achieve the goal. However, no one has ever invented a Turing complete declarative language, and there is good reason to think that such a thing is impossible (infinite potential problem domains).
Simonyi is a very intelligent and experienced guy, so he likely knows this. I hope he does; he should. So I like to interpret what he's saying as a grandiose way to say that he's hoping to make a big improvement in the art of programming -- there certainly is huge room for improvement.
But if he literally means he hopes to make all programming as easy as making powerpoint slides, then he is a fool or a liar (but he might still produce some cool tools).
(Making really cool graphics for the backgrounds of powerpoint slides is an art, BTW ;-)
