I wonder, as parallelism is exhausted too, will there be a point of reversion, were the cost of bad management practices on product and performance become so big, that the decision power returns to the experts who craft such systems? As in, the council of engineers vote no on middle managements eternal bloat for company internal status points? Else the users switch to engineer governed systems, as created by open source?
