That is a gamble. Everyone talks about how the dotcom bust quickly recovered and housing bust recovered. But that period was when smart phones started, everyone got broadband and most businesses moved to the web. Can you be surely something else will come along?
To me, it seems obvious the next boom 10 years out is in physical labor and being an advanced robot with your body. That is what will have value with the hugely deflationary knowledge work part going from super expensive to insanely cheap.
Better to be optimistic and make moves to position yourself for the “new thing that comes along” then to give in to despair. Then if it does come along they are ready to jump on that train.
In this case their is nothing lost with cautious optimism.
something has come along - the new fangled AI stuff.
People back then also didnt think the internet would amount to much when it first came out, and people also thought mobile phones were for business users not casual consumers.
Once you’ve automated manual labor and mental labor, what’s left?
