You still have not given me one reason Apple will lose market share because of Microsoft's early adoption of this applied AI software. I can use Safari to go to ChatGPT and ask it questions. Any API that is created to leverage ChatGPT will work on Windows, MacOS and Linux.Machine Learning Models (aka AI) combined with a browser are a new frontier for business. Like the original WWW ( which many saw as a passing fad) no one can predict what will happen next. If this tech can make humans more productive, it might turn out to be the most positive development in 200 years. Apple had Bill Atkinson’s HyperCard in 1985, but they were too insular to see its potential outside local networks — a $1T mistake.
Apple is not competing in this area as of yet. Microsoft was not either until it spent 20 billion to buy in.
