Anish Kapoor dominates this week's comments update, after calling for artists to engage with issues such as nationalism, Brexit and Donald Trump, and unveiling a giant whirlpool in Brooklyn.

Political descent: British artist Anish Kapoor's call for artists to tackle "real-world questions" in the current political climate drew a strong response from Dezeen readers.

Davvid was in clear agreement. "We all have to speak out against reckless and ignorant politicians. Trump is a disaster," he said.

"Extremely awkward, deflating aesthetic. Such a waste of a brilliant opportunity," expressed a disappointed Dominique Rickard.

Car crash: Elon Musk's latest idea – to dig tunnels and create underground tracks for cars in a bid to combat growing traffic levels – was met with bemusement in the comments.

Not all felt the idea was a none-starter, however:
