> ...Is this rate of change supportable? This is hard to project, as there is no definitive target, most of the changes that you describe are more like operational in their nature. Basically, it's an equivalent of planned obsolescence. Most of people can still operate hand screwdrivers, and have the job done, yet their preferred tool now may be powered. There are benefits, of course, and most don't bother noticing these transitions, as they may be occupied with higher level of problem solving. Another factor is that in software there's no really "ideal" form. Same material ideas can be shuffled ad infinitum, as in collidoscope, creating different feature combinations and looks. Perhaps, you did get to see quite a few and no longer feel excited with the rolls. But even for younger folks there have been many transitions in short time, like the fast pace of smartphone changes just in a less than 10 years. Maybe younger minds are more adaptable to quick changes.
