Is there a way you can isolate the "reasons that are well known" into "reasons that can be made to work even in non-Typescript situations"?

Or can the "reasons that are well known" be laid out for closer scrutiny and discussion?

Is it possible that there are multiple paths up the "massively improved productivity" mountain?

Any of these angles could help move the problem even further off the mark of "my subjective perceptions vs. theirs" and into the objective "our perceptions" zone through additional openness.

If this can't be done I'd guess you'd run into a lot of problems that are more psychological in nature. Generally when you say "here's a great thing," (especially if others think they have great ideas also) you get a backlash effect at the very least.
