What's interesting is how I opened Safari's reader mode to digest this 5000+ word polemic, and then noticed for the first time a new option to summarize its contents. A few seconds later I had a clear idea of what the author's thesis is, without being under the false impression that it had conveyed its finer points.
I read the article. After reading this comment I tried to get it summarised.
The result wasn't pretty. The summary claimed that there is skepticism over the security of Private Cloud computing, which the article actually praises.
Strange that we received two very different summaries. There was a part in the article where the author mentioned that Apple's private cloud compute claims were "literally impossible", but that was hardly the general takeaway of the article.
Mine basically said Apple has fallen short of their vision because of the inherent limitations in relying on web services.
