> Brutalism is a 1950’s architectural trend that was abandoning all decorations, and creating brutally simple buildings made from concrete. They often weren’t even painted to emphasize their brutal nature. So big, brutal blocks of concrete.

> It was the architects showing they were bored with the status-quo and trying something different. That feels very similar to the current search for the UI trend to take over design.

"Brutalism" doesn't come from "brutal" but from "brut", meaning raw or unaltered. It also had goals and values beyond being bored with the status quo, in that it was a close offshoot of modernism concerned with authenticity.

Although it's true that the name wasn't very good and it's now mostly understood to refer to the massive angular concrete structures we know and love.
