Thank you for sharing your in-depth research. Your design thinking process and research methods are gold.
I see the future of the design industry here. As you mentioned, one-size-fits-all attitude needs to change. Finding a middle ground simply won’t work because design solutions are based on different contexts.
As designers, we should always ask who the users are, how it is gonna be used, what kinds of devices, etc. If we realize that we are making too many compromises, we will have to stop creating one single solution.
