CHATGPT MOVIE London premiere is cancelled after complaints about using AI to script “The Last Screenwriter” ✨📽🎬

"Swiss director Peter Luisi employed the generative artificial intelligence chatbot to write the film and gave the AI the screenwriting credit.

Aptly enough for a script composed by an AI, “The Last Screenwriter” is about a famous screenwriter dealing with an AI scriptwriter named “ChatGPT 4.0,” outperforming him and somehow understanding humanity better than the actual human.

Luisi produced the screenplay through a series of prompts to ChatGPT, starting by asking it to “write a plot to a feature-length film where a screenwriter realizes he is less good than artificial intelligence in writing.”

He followed up with the AI by asking it to compose outlines and scenes, as well as name the movie’s characters. With some editing, the script was complete."

“As the screenwriter of 'The Last Screenwriter,' I am excited to bring this thought-provoking story to life on the page,” ChatGPT is quoted as stating.

“At its core, the film explores the intersection between technology and human creativity, and asks the question: can machines truly replace the human experience when it comes to art and storytelling?”

"The feedback we received over the last 24hrs once we advertised the film has highlighted the strong concern held by many of our audience on the use of AI in place of a writer which speaks to a wider issue within the industry,” the Prince Charles wrote in its statement."

Should we expect more pushback by the public, or for AI to gradually permeate Hollywood and music regardless?

AI DIMINISHING RETURNS or Moore's Law coming into effect? We hear both sides of this debate, making it tricky for businesses to know whether to wait or to invest further into AI now. Who should we believe? 📈✨📉

In this recent interview, Databricks CTO Matei Zaharia sums up some of the challenges that he sees with LLMs:

“Whenever you double your training costs, you increase quality by only around 1% or something like that.”

“Beyond the scaling law itself, there’s also the fact that we kind of put in all the data on the internet in these models already,” he added.

“Even if you repeat it and add more data, maybe you can modify it and create variants of it. However, it’s not clear if it would be that much more informative.”

Depending on how an organization is positioned, we see divergent views. Microsoft and OpenAI tend to be more bullish:

👉 Microsoft CTO Kevin Scott focuses on compute: “We are nowhere near the point of diminishing marginal returns on how powerful we can make AI models as we increase the scale of compute,” he said.

👉 OpenAI's Sam Altman promises continued progress: “We can say with a high degree of scientific certainty that GPT 5 is going to be a lot smarter than GPT 4. GPT 6 is going to be a lot smarter than GPT 5. And we are not near the top of this curve.”

For what it's worth, I don't like the term "smarter" in this context, but I'll take it as meaning "performant" and "more reliable" in more scenarios.

When some people refer to "quality", they often imply benchmarking results. These tests are of limited value, since they can be gamed with more fine-tuning and training.

As we focus on more edge cases, it becomes less viable economically to solve for all scenarios. Along with hyped up user expectations, this is one of the pitfalls of the quest for AGI with LLMs.

Performance without competence or understanding can only take us so far.

We know that LLMs come with structural limitations that make them unreliable for some applications. We understand that synthetic data has its uses but can introduce unwanted noise in the process.

Intuitively, investing billions into training brute force LLMs raises questions when it comes to ROI and monetization - setting aside the impact on energy costs or debates about copyright and privacy.

From mult-step (or compound) systems to “objective-driven AI” architecture, we're seeing plenty of initiatives to improve results.

In this context, it makes sense to focus away from LLMs for some (many?) applications.

Is it time to go back to the drawing board or to double down on LLMs?

How will AI economics stack up if we continue down the current path?

What if part of the answer lies in better organizing data and smaller models, rather than throwing faster chips and more resources at LLMs?
