I think this graph doesn’t have to move left to right, it can also move right to left. On several occasions it started to move up the “tech trigger” slope, but without any functional applications for the current technology the point slid back down to the left again.

I think the graph needs at least one more demarcated region. After “tech trigger” there needs to be “real world applications”. Without real world applications you can never progress past the tech trigger phase.
