From my point of view this is exactly what he mean. Especially in the first line of the post, when it says:

Is your job scalable? If not, it might become obsolete.

And in this part

Here is where the issue of scalability enters the picture. It matters none how good you are at your profession, it if can't scale digitally, it is severely limited.

That's why I believe Any job that is not scalable will be obsolete!!

About this part "Any trade or profession that cannot adapt to tokenization and new paradigms is doomed to become extinct or be replaced by something else" Is only my impression, my interpretation about he was saying, or my feedback, if you will!
