Feels reasonable in the first few paragraphs, then quickly starts reading like science fiction.
Would love to read a perspective examining "what is the slowest reasonable pace of development we could expect." This feels to me like the fastest (unreasonable) trajectory we could expect.

The slowest is a sudden and permanent plateau, where all attempts at progress turn out to result in serious downsides that make them unworkable.
