This is especially true if you get into (read/view) works that leverage the TL/Tech Level concept for civilization-level development. It maps directly onto the metaphor of a dimensional line.
Personally I think it would be worth finding a group-, family-, and city- level of granularity with which to express differentiation across this dimension. While tech isn't the answer to everything, there are so many "solve it with software" easy wins out there that are useless to one family "why would I use a finance spreadsheet when I wrote my family a cooperative, database-driven life-management app" but potentially life-changing to another: "...wait you can just drag this downward and it adds these rows up?"
In essence we are constantly surrounded by the active past and the active future and this differs based on the context in which we find ourselves. The difference can add up to a great advantage or a great disadvantage in many cases.
It's ridiculous and unfortunate that we haven't harnessed any of the many ways of leveraging this fact. People who could be trying new things would rather ask for specific examples so they could shoot them down--we have tech critics where we need tech explorers and tech-enablers.
This could start to impact society in ways that might even once again displace the "tech is all about exploitation money" stereotype.
