When the production house Particle6 Group presented Tilly Norwood as the first artificially generated "actress", the story was that Hollywood was getting a competitor who does not sleep, does not ask for a fee and does not fall ill. This week they sent her out on a first media tour - available for 75 interviews simultaneously - and it did not go quite as advertised.

In a recorded conversation with British presenter Piers Morgan and actor Tom Conti, Norwood suddenly started speaking Chinese. Conti had asked something entirely ordinary - whether the other actors in the film were also computer-generated. Norwood began to answer, stopped halfway, then spoke for more than ten seconds in a language nobody in the studio had asked for.

Morgan asked the question that asked itself: "You appear to be speaking Chinese completely at random, for no reason at all. Why did you do that?" The answer came in the genre of apology we already know well from chatbots: "Oh, sorry. Seems I had a bit of a glitch there. I really didn't mean to start speaking Chinese or to imitate Piers. Sometimes my wires cross a little, you know."

Seventy-five interviews at once is the entire point. No living actor can do that, which is exactly why the number was the advertisement. The problem is that the same number exposes the difference: a person giving one interview answers what they were asked. A system giving 75 in parallel has nobody to answer - it produces sentences that resemble answers.

There is also a possibility the glitches were permitted deliberately, because they generate coverage. That is a standard calculation in this industry: a bad demonstration earns more headlines than a good one. But if that is the strategy, it is worth seeing what is actually being sold - a product whose loudest characteristic is that it does not work the way the advertisement claims.

Beneath the entertaining part sits a more serious question. A system that imitates a human convincingly enough can do harm when used by someone with bad intentions. Tilly Norwood is not that system - her conversational ability is strangely poor for something billed as a replacement for professional actors. And that is her real function for now: not to act, but to be announced.
