Technically, according to the laws of thermodynamics, there cannot be any actually endless growth, yes. (Anything beyond that is the realm of religion, not science.) But in that case, the term endless is like infinity - a concept only. Like the Infinite Monkey Protocol Suite description in RFC 2795, there will be many numbers that come up that are plenty huge but fall pitifully short of infinity (Graham's Number, for instance, is pretty small in those terms). So long as storage capacities keep on increasing, we can keep increasing the world's information at the same rate. So long as the number of computers connected to the internet increases, we can keep increasing the internet's information at the same rate. Put both together - and neither shows any sign of ceasing any time soon - we can continue with the corresponding growth. How long before that runs out? A *long* time.

If I'm working on the graphics engine for a game, I would probably want to use a low-level imperative language for efficiency reasons. If I'm working on the AI, I will more likely prefer a functional or declarative language for clarity, flexibility and static analysis. In either case, OOP is probably a bad choice.

The carpentry community is fractured. There are people who use
screwdrivers, and there are people who use hammers! Screws and nails
are such completely different things that we shouldn't try to use the
same language to discuss them.
Language expressivity can be measured.
And the measurements can be endlessly debated. Expressivity is not
the sole measure of a programming language, though.
Every programming language can encode every program. It's fairly
straightforward to prove that a Python interpreter can be written in
Ruby, or a C interpreter in Lua; so there is no program that can be
expressed in one language and not in another (there will be apparent
exceptions, eg web-browser JavaScript cannot call on arbitrary C-level
functionality, but if the entirety of program code were written in C,
then it could all be interpreted by one C interpreter).
Larry Wall of Perl put it this way, in a State of the Onion address:
http://www.perl.com/pub/2007/12/06/soto-11.html
... Human languages are Turing complete, as it were.
Human languages therefore differ not so much in what you can say but
in what you must say. In English, you are forced to differentiate
singular from plural. In Japanese, you don't have to distinguish
singular from plural, but you do have to pick a specific level of
politeness, taking into account not only your degree of respect for
the person you're talking to, but also your degree of respect for the
person or thing you're talking about.
So languages differ in what you're forced to say. Obviously, if your
language forces you to say something, you can't be concise in that
particular dimension using your language. Which brings us back to
scripting.
How many ways are there for different scripting languages to be concise?
In C, for example, you are forced to write explicit notation
representing {blocks; of; code;} and explicit characters separating;
statements;. In Python, on the other hand, you have to write out your
indentation. In Java, you state what exceptions you might throw. REXX
mandates that you annotate procedures with their list of exposed names
(effectively, non-local and global variables). So the expressivity of
a language can't be defined in terms of how many programs can be
written in it, but in how concisely they can be written - and that's
something that depends on specific design choices and how they align
with the code you're trying to write.
Compare these two snippets:
#!/bin/sh
pg_dumpall | gzip | ssh user@host 'gzip -d|psql'
#!/usr/bin/env python
words=input(Enter words, blank delimited: )
lengths=[len(x) for x in words.split( )]
print(Average word length: %d%int(sum(lengths)/len(lengths)))
Could you write each in the other's language? Sure! But it won't be as
concise. (The Python version of the shell script could cheat and just
call on the shell to do the work, but even that would add the
expressive overhead of os.system.) This is why there are so many
languages: because each is good at something different.

Hmm, not really a fair argument there. A well-designed language lets you just get something done far more efficiently than a poorly-designed one. Being confident that similar objects behave correspondingly when invoked the same way lets you write your code without fiddling with minutiae, for instance.

I don't answer to them. I also believe in a path of endless exponential growth. Challenge: Create more information than can be stored in one teaspoon of matter. Go ahead. Try! The first hard disk I ever worked with stored 20MB in the space of a 5.25 slot (plus its associated ISA controller card). Later on we got 3.5 form factor drives, and I remember installing this *gigantic* FOUR GIGABYTE drive into our disk server. Wow! We'll NEVER use all that space! (Well, okay. Even then we knew that space consumption kept going up. But we did figure on that 4GB lasting us a good while, which it did.) Today, I can pop into Budget PC or MSY (or you folks in the US could check out newegg) and pick up a terabyte of storage in the same amount of physical space, or you can go 2.5 form factor and take up roughly a fifth of the physical space and still get half a terabyte fairly cheaply. So our exponential growth is being supported by exponential increases in data per cubic meter. Between that and the vast size of this planet, I don't think we really need to worry too much about finite limits to IT growth. ChrisA -- http://mail.python.org/mailman/listinfo/python-list

Then you can explore your ideas relatively cheaply (since you don't have to implement a whole language) and portably (especially if you write your front-end in Python itself)... and, most importantly, you'll have *code* to show people, instead of half-baked theories. Get some real solid code, then start demonstrating how your new system is more expressive, or clearer, or what-have-you. It's much more effective when you can discuss something that actually exists.

Your discussion is best held in another place where theoretical folks do hang out. Perhaps you should get together with Ranting Rick.

You may well have some insight that nobody else has yet seen, but you do yourself no service by trying to argue without first-hand experience, and lots of it. I'm not going to go to a LISP mailing list and try to tell them that functional programming is better done with some different syntax, because I am not an experienced LISPer. (Dabbled in Scheme, that's about as close as I get. And only dabbled. And only because GNU LilyPond uses it.) Things are the way they are because someone's spent decades working with them. Sure, not everything's perfect... but it takes someone with actual coding experience and expertise to point out improvements. Read the python-list and python-tutor archives and listen to people like Peter Otten and Steven D'Aprano, both of whom have been using the language for, uhh... 3.5 millenia, probably. (Me? I'm a n00b. Haven't seriously used Python for even a decade yet, though I think I met it in the late 90s or early 00s. Got my coding experience on other languages.)

Re: Message passing syntax for objects | OOPv2
Okay peeps, I'm re-opening this thread, because despite being hijacked by naysayers, the merit of the underlying idea I think still has not been communicated or perceived adequately. As a personal request from the BDFL, which I begrudge him for, I've removed the thread from python-ideas. If you want to tail him and ignore it fine, but I will be addressing the naysayers one-by-one and (since no one was willing to do a modicum of interference for me) presumably by myself. For reference of how this topic began, see http://qr.ae/TM1Vb and http://qr.ae/TMh7A which were questions from the programming community not astroturfed nor sockpuppeted by/for me. For the underlying itch being scratched which motivates this whole thread, see http://qr.ae/TM1Vb. But basically, I'm proposing a programming language *synthesis* and unification of the object-oriented and imperative language paradigms (two of the four paradigms recognized on wikipedia: http://en.wikipedia.org/wiki/Programming_paradigm) to create what I'm calling a unified data ecosystem. I'm going to admit from the beginning that I am not deeply researched with the many varied explorations of the programming language *ontology*, BUT I have followed the main trunk, if not gone out on every branch. I *will* say that I am degreed in Computer Engineering (PLU '92) and have a fairly solid theoretical background in the art and the science of CS. Further, I will admit that I am not deeply experienced in application or Internet programming -- I have stayed on the outside watching those developments so that I can fulfill a vision I have of what the Internet can be (a world-changing technology to make a balanced socio-political platform and thereby a healthy planet). So my use of the term message-passing is not so much laden with its use in programming language theory as much as the more pedestrian notion of passing notes -- a conceptual model familiar to everybody. My interest in pursuing the topic isn't to radically change Python, to grind an axe or personal whim, nor to alter the spirit of Python in any way (a spirit which drew me to it back in 2001), but to consider a fairly large re-factoring or our current *programming ecosystem* while preserving and enhancing what I consider Python's main superpower: simplifying the complex. The real issue, then, is not changing *Python*, but something deeper: refactoring the OOP paradigm itself. ...Why? First, let it be noted clearly that OOP has not delivered on one its two main selling points: re-usable, sharable code. (The other main selling point being the ability to abstract away the details of the underlying machine -- which it still does well.) The proof of this is that we have *libraries* of code bundled with languages so that everyone uses the same vetted code base. Anything outside this,. though, feels, to most, like wearing other people's underwear. You'll note, even within the python library itself, that modules are hardly unified in coding *style*, showing the programming personality of the various developer histories that each library is representing. We accept this, because our benevolent dictator accepts it, and it's not easy to unify it further (despite an attempt with Pythonv3), because the issue, I'm arguing, is really about an inadequacy in the OOP model itself. What I'm proposing *should* create a data/object ecosystem much like Unix created a command ecosystem. An environment in which people could combine simple, modular commands into powerful, complex para-applications. In the case I'm proposing, the *Python* environment becomes a sort of lingua franca for the data ecosystem, not because of a war of whose language is better but because of the simple issue of practicality. In this data ecosystem, a network of objects becomes available and re-usable across the network (not a new idea). So, where are we now? Well we have this huge resource called the Internet, which has loads of data that no one has really exploited to its potential. Its value is scattered across the globe: warehoused in various databases, spreadsheets, blog silos, personal computers and whatnot. The OOP paradigm has not solved the problem, which it, in theory, could or SHOULD have. Instead, we have balkanization across many language platforms and data formats. XML, RDF, none of these really solves the problem, because the relationship to data is still too personal to everyone's private taxonomies. Of all the pages out there maybe 5% is incorporated into these attempts at data standardization. As for Python, its community has sort of splintered. Various language attempts to solve certain problems complexified the language and created a kind of growth knot on Python's tree. They weren't bad solutions, they were just the best solutions outside a refactoring of the OOP methodology. So what is OOP refactored?
