We also have this idea now that spending an afternoon with some tech is enough experience to share with others. Initial learning curve and "am I immediately as productive as I wish I was?" have somehow become key metrics.
True. It cuts both ways though (I guess like most things).
That is, once a person has invested in that learning curve and spent significant time working in a tech, tunnel vision tends to set in. It becomes the only tool, which that person fiercely defends. They've now got too much invested to just let it go.
It's actually not unreasonable from a raw self-preservation/self-interest perspective, but I do think it contributes to a lot of the emotion-filled tribalism we see. In other words, the intensity comes as much from interest in maintaining self-relevance and personal financial security as from the viability of the actual tech.
