Summarise a Long Article Into Three Things Worth Remembering

You read the whole thing, nodded along, and by tomorrow will remember roughly none of it, because a full recap is not the same as knowing what mattered. This picks exactly three points worth remembering a week from now, states each plainly, and says why it is actually useful rather than just repeating what the article said.

Read {ARTICLE_TEXT} and summarise it as exactly three things worth remembering a week from now, not a general recap of every point made. For each one, write one plain sentence stating the point and one plain sentence on why it actually matters or how it could be used.
