Apple, Google, Amazon can build a similar large language model easily enough within a year. ChatGPT is useful for a limited set of tasks, the real gains will be integrating this sort of technology into other software stacks to do more than just creative writing. This will take adding additional task specific machine learning as you're seeing Microsoft attempting to do. But Microsoft should also be a bit of a cautionary example, it shows that it's not actually that "simple" to get a language model to work reliably for new complex tasks.
