In my own job, I straddle cloud-based and local machine-based software. Overwhelmingly, the cloud-based software is slow to the extent that it removes at least 40 points of IQ and offsets a decade of experience. The intellect and mental speed I have spent a lifetime building are simply washed away by latency that shuts my mind down, effectively turning me into a ninth-grader. Sure the company pays me as if I continue to generate output becoming of my generous salary. But I maintain the illusion simply by spending many hours on weekends with copious amounts of coffee and, at times, gin, doing work on cloud-based software that, on the "outdated" local software, used to take minutes.
Cloud software is among the biggest frauds ever perpetrated on the American consumer.
