Later in the talk, he discusses how critical prices occur. When drugs were first released to combat AIDS, they were quite expensive, surpassing $10,000. Within just a few years, generic drugs drove the price down to $0.55 per day, allowing many more people to receive them. Basically, the longer a technology is around, the more value it loses.
Per Anderson, almost all technologies will drop so far in price that they will become somewhat free. Example- the music industry. Whereas people used to pay $0.99 per song for music, they now pay roughly $8 for unlimited music on services like Spotify or Apple Music. To view the talk yourself, visit here.
