That climate makes both businesses and developers afraid to invest resources in potentially defunct technologies. Remember when WinForms was replaced by WPF? Only to be replaced by Silverlight? Then by Windows Phone apps? Which were replaced by Universal apps? Or what about how Web Services were replaced by WCF only to be replaced by Web API?
