doesn't it seem like these models are getting to the point where even conceiving their training and development is less and less possible for the general public?

I mean, we already knew only a handful of companies with capital could train them, but at least the principles, algorithms, etc. were accessible to individuals who wanted to create their own - much simpler - models.

it seems that era is quickly ending, and we are entering the era of truly "magic" AI models that no one knows how they work because companies keep their secret sauces...
