Synthesia has built a large business around synthetic video presenters, giving companies a way to produce training clips, announcements, and instructional material without cameras, studios, travel, or the repeated availability of a human speaker. The Economist's profile of the London unicorn points to the obvious attraction. Corporate video is expensive, slow, and often visually dead before anyone presses play. An avatar that can speak many languages and be revised by editing text solves a bureaucratic problem with brutal efficiency.

The cultural cost appears in the same gesture. A company that once staged authority through a manager, actor, or expert can now generate a face that carries the message without carrying a biography. This suits compliance training, product updates, and global HR, where the speaker is already half a template. It also narrows the distance between communication and ventriloquism. Synthesia's restrictions on political misuse acknowledge the danger, but ordinary corporate use is already a lesson in synthetic authority. The employee watches a face that never waited in the building, never took responsibility for the policy, and can be reissued tomorrow in another language with the same calm mouth.
