I don't understand this comment at all. "At least 1000 words" would require at least the skills of writing decently & writing a moderate amount based on little. I get that getting to exactly 1000 requires some skill, but how on earth is that the only skill involved?
fwiw, this entire thread exists because of the ignored [2] in the link.
[2] Write 1,000 words about it by August 31st, 2026.
this is 1 of the two constraints. you may have to rework sentences. the skills exercised are these efforts
It's relatively easy to write many words, but it takes more skill to express the same message with fewer words, like how video compression needs more time for fewer bytes and same quality. As Pascal once wrote, "If I had had more time, I would have written a shorter letter."
