Hmm... A really new area of economic activity (vs. farming, mining, transportation, ...), often supported by huge economic bubbles, frequent indifference to viable business models, a now-large workforce often commanding pay 3x or more what "normal economy" workers make and often expecting annual pay growth >10% higher than inflation, generally underwhelming contribution to human welfare (shinier things to click on every year is not a basic human need, nor does it seem to overall improve human society that much), ...
I'll say 95%.
I recall the incredible churn and waste of computer printer hardware ~~1985, when things were moving from daisy wheel printers to 9-pin printers to 24-pin printers to 300dpi laser printers to 600dpi laser printers. Sure, 600dpi laser output is more flexible & nicer than daisy-wheel output. But between all the effort of the replacement cycles, and working equipment with remaining service lives totaling many millions of years ending up in landfills... And let's face it - the main motive behind it was a zero-sum human nature "my tail fins are longer than yours" Red Queen's Race.
