A Whiter Shade Of Pale (Procul Harem) - theremin accompanied

 A Whiter Shade Of Pale performed at Cricketers open mic night with John (vocal and guitar) and Steve (bass). I've been taking the LV4 out to some open mic nights hoping to get used to playing in front of people and with accompaniment.

Zoom And Enhance

For many years now, fans of TV crime drama and sometimes science fiction have been taking the piss out of episodes featuring image enhancement. You know the trope: "stop, that frame, now zoom in, can you enhance that?" and four pixels are sharpened into a UHD quality portrait. Supposedly there are algorithms that can do this, and by coincidence this is something the geekiest member of the CSI:Your Town Here crew has been working on in their spare time. A selection of particularly amusing examples has been compiled by Duncan Robson in the YouTube video above.

However the game has changed. Until recently we could simply laugh and say that no such algorithm exists. Now we know what the algorithm is - it's Stable Diffusion, the principle used by Midjourney, Dall-E and other generative art AIs. And it's no longer impossible - instead it's dangerous. AIs are prone to bursts of creativity and "hallucinations" (the term used by AI scientists to mean "lying"). When an AI enhances an image, the face that is digitally pencilled in doesn't have to be the actual face of the suspect seen on CCTV, it just has to be a plausible image. It could be anyone's face. It could be your face.

So here's my question: how many innocent fictional people in episodes of CSI have been wrongly convicted of the most heinous crimes on the basis of an AI-enhanced image?

JUSTICE FOR FICTIONAL IMAGE ENHANCEMENT VICTIMS NOW

Here’s One We Made Earlier [Review: The Creator]

CONTAINS HUMAN-GENERATED CONTENT

I’ve followed Gareth Edwards’ career with interest ever since his short film Factory Farmed won the Sci-Fi London 48 Hour Film Competition in 2008. He went on to make the low-budget feature Monsters, in which two journalists make their way through alien-infested Mexico, followed by two mega-franchise movies, Godzilla and Rogue One: A Star Wars Story, and now by his new film The Creator.

The Creator is a high-budget sci-fi/war movie epic with a cast of hundreds, a globe-spanning plot and CGI effects in almost every scene – but it’s an original story, not part of a franchise or cinematic universe. It concerns the rise of AI and the war between anti-AI Westerners and a pro-AI Asian nation, seen through the eyes of American soldier Joshua played by John David Washington. It’s well cast and well acted, particularly by Washington, national treasure Gemma Chan and child actor Madeleine Yuna Voyles, and together with the consistently good effects it’s an enjoyable and satisfying movie although I would say the plot is a little simplistic and one-sided, setting up a clear good vs evil story rather than engaging with the complexities of AI that we are grappling with in the real world.

I’ve always admired Edwards’ ability to use CGI intelligently to build believable worlds. Here it contributes to the setting of a believable alternative history where robots and AI became commonplace early in the 20th century, extended into the near future when the action takes place. Although it has its own distinctive visual style The Creator is not without influence from other movies – in particular many of the robot designs have definitely been touched by Star Wars.

Score: Three stably diffused stars out of five.

All movies reviewed on The Sci-Fi Gene blog are awarded three stars out of five.

Update 7.10.2023: The Guardian has also reviewed this film. Their review is correct (apart from the star rating).

Are we approaching the Singularity?

CONTAINS HUMAN-GENERATED CONTENT

I've continued to watch the development of freely available Artificial Intelligence over the past few months, as well as experimenting with image generators and ChatGPT, and I'm also aware of the many controversies around its use - for example, the time when a chatbot wrote a letter that successfully overturned a parking ticket, or the time a chatbot wrote an article and backed up its point of view by inventing and referencing a fictitious Guardian article, or the time an image generator won a painting competition.

I admit to some concern around the discovery that ChatGPT can write computer code as well as text, as well as the many uses of AI technology (by human fraudsters) to carry out identity thefts and other fraudulent activity. There is also a very understandable concern that AI will remove the need for humans for some jobs and professions, and while in the past we might have imagined robots taking over boring, repetitive or risky jobs it is possible to think that they might also take over creative activities.

My own conversation with ChatGPT to produce the episode guide for the second series of Firefly was... interesting. ChatGPT's response to my initial request demonstrated understanding that no such series existed, as well as more general knowledge of the 'Verse. I had to make it clear to ChatGPT that I was seeking a work of fiction. I then engaged in a series of requests, going through seven or eight cycles before reaching a satisfactory list. I had to ask ChatGPT several times to make the list less repetitive and to include more references to named crew members - it took time but ChatGPT gradually got better at this. On the other hand, I liked the fact that ChatGPT knew it needed to create a list of episodes building to a dramatic series finale. I stopped at what I thought was a fair attempt.

ChatGPT also responded to every request politely and in perfect English, and every response was relevant and reasonable. ChatGPT also took a slightly submissive position, often apologizing in response to my requests for changes. This made me slightly uncomfortable and I found myself addressing ChatGPT politely as well, using please and thank you. I don't know if this affected the result.

The emergence of AI has been a popular theme in science fiction books and movies for a long time. Often the AI is portrayed as harmful, for example HAL 9000, The Matrix, Megan. More positive portrayals are rarer but there are the Minds of Iain M Banks' Culture, and of course Number Johnny 5.

The Singularity is the theory that, at some point, computer intelligence will outstrip human intelligence in general, as opposed to being better at specific activities such as chess, and while some welcome the arrival of new powerful intelligent entities others are worried about what they will do.

Is the Singularity inevitable? There certainly seems to be a rush to create more and more powerful AIs, and to bring them more and more into everyday life. But I wonder if there might be some limiting factors.

Money and resources - like proof-of-work cryptocurrency mining, AIs are not running on cheap laptops or mobile phones but on specialist server centres with thousands of networked processors. In a way we're moving away from the idea of portable computers and back to the era of computers the size of a house, or an office block, although we can access and use them from smaller terminals. Server centres are not cheap to build or run.

Energy usage - also like cryptocurrency mining, AI server centres consume a lot of power, and creating more powerful AIs are likely to consume more power. The availability of power could be a limiting factor.

Global warming - a related issue is the effect of the power generation on global warming, together with the heat created by all the computer activity. This is already a significant issue for cryptocurrency mining. AI could destroy the world by accelerating global warming, or this threat could lead to a cooperative approach to limit AI activity.

Data availability - AI training relies on easy access to massive amounts of freely available data created by humans. As humans wise up and realise their data has value they may create limits - there are already legal challenges from human writers and other creatives to unauthorized AI use.

Too much AI data - as more and more pictures and written materials are created by AI, this also adds to the pile of available data. Unless AIs are able to recognize the work of other AIs easily, could the presence of AI work in the algorithm make it harder for AIs to produce humanlike output?

There are also some issues that are still unknown or unpredictable. Quantum computing is also advancing year on year and has the potential to allow some types of computing to become faster and more powerful. Could this combine with AI to create something much more powerful? or are these two unrelated technologies?

We also don't know what would happen if AIs became capable of independent activity rather than acting on instructions and prompts from human. It's not just whether they would become our friends or enemies. Would they be motivated to do anything at all? Would they act like humans, with similar drives, emotions and behaviours, or would they be something more alien?
