I think there are other reasons something didn’t happen 10y ago. - No one thought of it. - Someone tried, but the implementation, execution, or something soured the project, not the foundational idea. - The world wasn’t ready for it. This could fall under social trend, but I think it’s its own thing. - Something might exist that’s “good enough”, until something better comes along that shifts the market. The iPhone is a good example of this.
