It's not at all extraordinary if you understand how they're trained. For math and programming it's possible to generate an infinite amount of training data with correct answers, as compilers and theorem provers can guarantee correctness. For writing, the quality is not objective, it's determined by human preference, so you need humans in the loop, which slows things down massively and limits the amount of data that can be generated.

Microsoft has completely lost the ability to make good software; see Microsoft Teams and what they've done to Windows 11. Apple don't have a foundation models team so they're limited to using other people's models, which handicaps them as they can't do vertical integration like with their other products. Google hasn't made a single competitive consumer product in the past decade, but has certainly killed a few.

Is Elon Musk doing their pricing?

It has better judgement in math and coding, which have infinitely generatable training data; if you ask it a domain-specific question about something like sales or marketing, its answer is often horrendous.
