• What is the future of advertising? Sora might have the answer to that

  Sora, a new service from OpenAI that produces one-minute videos in response to a textual prompt, is not yet available to the public. However, the videos it has released are striking for their vividness, detail and — if this is the correct term for artificial intelligence (AI) — imagination.

  It is worth considering the future economic consequences of this development.

  First, Sora is unlikely to put Hollywood out of business. Eventually these videos could get much longer, but it remains to be seen how well AI can construct long story arcs and integrate them with images into a commercially appealing package. That still seems a long way off, and cost is an additional consideration.

  The more clear and present danger to Hollywood is that would-be viewers might start making their own short videos rather than watching television. “Show my pet dog Fido flying to Mars and building a space colony there” is perhaps more fun than a TV show to many.

  Sora and comparable services could lead to a proliferation of short educational videos, internal corporate training videos and just plain fooling around. Sora would probably be good for TikTok and other short video services. It is not hard to imagine services that splice your Sora-constructed videos into your TikTok productions. So if you are doing BookTok, for example, maybe you put a battle re-enactment in the background of your plug for your new book on the US Civil War.

  Perhaps the most significant short-run use of these videos might be for advertising — especially Internet advertising. Again, there is the question of how to integrate narrative, but the costs of creating new ads is likely to fall.

  More advertising might sound like a mixed blessing. However, ads would almost certainly be more fun and creative than they are now. Watching ads might become its own aesthetic avocation, as is already the case for Super Bowl ads. These ads also might be targeted, rather than serving a mass audience. If your Internet history suggests you are interested in unidentified aerial phenomena (UAP), for example, perhaps you might see ads with aliens telling you which soap to buy.

  Some other implications of Sora are more subtle and more speculative. There is the notion that Sora has been trained on “synthetic data,” for example, which means other videos created by AI, rather than videos of real life. To the extent that is true, future AI progress might be to some extent liberated from constraints of data. AI tools might be in essence able to teach themselves, which would accelerate AI progress even more.

  To the extent synthetic data proves important, it might weaken the moats of Meta and Google, which have access to significant stores of data through Facebook, Instagram, YouTube and other services. That would give start-ups and smaller AI companies more of a competitive chance. On the other hand, the rising demand for computation — to produce and work with the synthetic data — would strengthen the market valuation of Nvidia and other companies selling the proper kinds of chips.

  It is also interesting to think of Sora as a new way of modeling physical systems. Its presentation of physics and geometry is by no means perfect (though likely to improve), but it is already good enough to fool the typical human eye. Whatever methods were used to model the physical systems of our world seem to apply quite generally, keep in mind that OpenAI has not explained how it created Sora.

  In any case, those methods might someday contribute to building better models in physics, chemistry and engineering, and could accelerate scientific progress as well as economic productivity.

  Finally, Sora is yet more evidence that, in AI, progress in images is proceeding more rapidly than progress in text. GPT-4 has now been out for well over a year, and it remains to be seen how much better its successors could be. In that same period of time, image and video production has made amazing strides. It was not so long ago that people used to complain that AI image services could not portray human hands convincingly. If progress in images continues to outpace progress in text, then maybe that old saying has it backwards: A word is worth 1,000 pictures. Or, to put it another way, words are more truly “human” than images.

  At the most speculative level, the success of Sora might increase the chance that we are living in a simulation — a computer-based world created by some high-powered being, whether a deity or aliens. Is that bullish or bearish for asset prices? It depends on how you assess the responsibility and ethics of the creator. At the very least, our planet Earth simulator seems to be able to generate videos that last longer than a single minute. Beyond that, I cannot say.
