This technology will be embedded into every OS within 2 years. People don't generally need a "super" model like GPT3/4. It will be perfectly acceptable and common to have the model change context, sync with whatever model/training data is necessary to be an expert in that context only, and associated contexts..., and prompt it in a specific domain. Client devices and internet connections are fast enough to do this in near real time today. The platforms to do all of this are being built right now by every company that creates software otherwise they will fail within 5 years.

It's an inconvenient truth, for better or worse.
