While I will not say that Bitcoin will not have its place, I look at things from the technological perspective. As a technology, Bitcoin was 1.0. We are seeking to improve upon it.
Alt-Coins are where the development is taking place. To think that Bitcoin will be the "Money of the Internet" is absurd. We are gong to see millions of currencies used.
As we delve deeper into Web 3.0 and some of the more advanced technologies like bio=engineering and genome sequencing, these will not be run on Bitcoin.
I love the picture you paint. It is ironic I was thinking something similar for a post in the morning explaining it in a different manner. Ultimately, we need thousands of projects with thousands of groups of whales.
If we take a look at Steem/Hive and the tokens around it is clear what is happening.
This is a very small space and yet we have a hundreds of tokens. Sure a lot of them are struguling to get any value, but from hundreds, some will succed.
So yes, I agree there will be countless of tokens and projects around.
