@semanticist (the irony is not lost that these enormous failed megaliths developed from many of the same ideas that powered—and hamstrung—smalltalk!
and all these things were ideas worth trying, because contact with the real world is absolutely vital (which is why "failure of imagination" is a cheap and unfruitful argument).
but as we still see, software companies have incentives to push their latest darling ideas as "the future", whether they have tried them in the real world or not.
