I can see how the word "revolution" in the context of this list has acquired so anemic and castrated a meaning.  I am sorry.  Next time, I will use a word that means all the way around, or when a king is replaced by a democracy. time.

Now we're getting somewhere that actually has some vague relevance to  
the list.

If I ask the same questions multiple times you can be sure that  
they're not rhetorical.

So for you, for something to be 'revolutionary' it has to involve a  
full paradigm shift? That's a more extreme definition than most people  
use.

 From a pedantic, technical point of view, these days if the processor  
is being used that little then it will ramp down the clock speed,  
which has some environmental and practical benefits in itself. ;-)

You haven't looked up what content-aware fill *is*, have you? It's  
based on the same basic concepts of pattern-matching/feature detection  
that facial recognition software is based on but with a different  
emphasis.

To paraphrase, it's not facial recognition that you think is the only  
revolutionary feature in photography in twenty years, it's pattern- 
matching/detection/eigenvectors. A lot of time and frustration would  
have been saved if you'd said that in the first place.

You're jumping too many steps here - object recognition concepts are  
in *widespread* use in consumer software and devices, whether it's the  
aforementioned 'focus-on-a-face' digital cameras, healing brushes in  
many different pieces of software, feature recognition in panoramic  
stitching software or even live stitching in some of the new Sony  
cameras.

Semantic processing of content doesn't magically enable a computer to  
initiate action.

Combining pattern-matching with adaptive systems, whether they be  
neural networks or something else is another matter - but it's been a  
long hard slog to find out that this is what you're talking about.

Adaptive systems themselves are also quite widespread by now, from  
Tivos learning what programmes you watch to predictive text on an  
iPhone, from iTunes 'Genius' playlists & recommendations through to  
Siri (just bought up by Apple, as it happens).

That's a really REALLY bad analogy. FBW is a pilot-initiated control  
system. It's smaller/lighter (the initial reason for it's use) and it  
reacts to changes faster than the pilot can to stop stalls etc, in a  
similar way to ABS systems in a car reducing the chances of a skid. It  
doesn't *initiate* anything in itself, it's 'just' a moderated control/ 
feedback system.

This sentence makes no sense. Did you mean 'process' rather than  
'encode'?

I like William Gibson or Stuart & Cohen as much as the next SF fan,  
but again you're taking too many steps at once.

Emergent behaviour from a complex system (such as bypassing letter  
writing by finding another way of communicating or reason for doing  
things) is *emergent behaviour* - by definition you can't predict what  
form it will take and you can't *plan* for it. You can't even plan  
that it will *happen*.

In the same way, setting up a protocol for a network doesn't let you  
predict that most internet traffic some years later will be via  
Facebook or MMORPGs.

Having now looked in a number of dictionaries on and offline, I stand  
with Richmond's response. In common usage it's a word with very  
specific connotations and they aren't ones that people associate with  
software. With Steve Jobs, perhaps, but not with software. ;-)

> Software feature creep is not really evolving software.

That's a matter of definition. Within the photography field, apps like  
Aperture and LightRoom have had huge impacts on people's ways of  
working (often making whole suites of other apps redundant in one go),  
looking at a wider field the explosion of geolocation features and  
services has revolutionised mobile devices and our interactions with  
them, multi-touch devices are giving us new ways to physically  
interact with computing systems.

1. Much of what you're talking about as a final aim is emergent  
behaviour - you *can't* predict what will or won't happen, or when.

2. We've already been through the substantial increases in  
productivity that the expense of computing requires. Increased  
productivity isn't the problem - *expected* productivity is the  
problem because it automatically increases as productivity increases.

3. Adaptive systems don't just happen. They need to be trained, and  
for the level of abstraction you're talking about they have to be  
trained *a lot*. From a pragmatic point of view, much of that  
increased productivity will be swallowed up by learning to be a good  
system trainer, in the same way that certain types of information  
research have been vastly increased via the net, only to be swallowed  
up in learning to use search engines efficiently and learning how to  
winnow out all the chaff.

4. The level of independent action you appear to be happy with in a  
computer gives most people the screaming heebie-jeebies and flashbacks  
to "I'm sorry Dave, I can't do that".

5. Most importantly, your entire body of communications on the list  
appears to miss out a vital step - how do adaptive systems magically  
morph into systems capable of initiating actions without user or  
programmer input? I'm uncomfortably reminded of S. Harris's 'then a  
miracle occurs' cartoon. :-(

6. On a slightly more tongue-in-cheek note, enjoy the minutes between  
the first ubiquitous 'self aware semantically self optimized pattern  
engine' and dying/transcending/experiencing "It's life Jim, but not as  
we know it" in the ensuing technological singularity. ;-)

P.S. It's 'rote', not 'wrote'. I know it's just a typo, but it's one  
that drastically alters some of your sentences._______________________________________________
