IMHO what you should be doing is building stuff to show off.
More great ideas will flow out of that activity.
As for missed the boat, how do you mean? We remain in early days!
Finally, try to avoid making your own reality. You write as if you know the future, and none of us do!
And even when we are right, how we respond to that future really matters!
You could sulk in gloom
, or!
You could be building things and or showing them off.
It is that showing off that nets good new opportunities.
