To simplify the issue here: Amazon made buying books 10x easier, and expanded the easily purchasable selection by more than 10x.

Mastodon doesn't make anything 10x better or easier. It will never gain mass adoption accordingly. Mainstream users will never care about it, not under any circumstances.

It'll languish as just another techie fantasy, with every other decentralized premise (not one of which has ever acquired mass consumer use, not in decades of trying). It's the standard techie failure to understand average users. The same reason techies for nearly two decades have been baffled as to why average people haven't adopted command-line Linux - they can't be objective and properly put themselves into the shoes of other non-tech people.
