'Tech CEOs are like cult leaders' – the artists taking on Facebook and big data

Langlands and Bell are celebrating their 40th year together - by taking an uncompromising look at Silicon Valley's utopian promises

By a remarkable coincidence, on Wednesday, right as Mark Zuckerberg finally addressed the unfolding Facebook data-breach scandal, British artists Ben Langlands and Nikki Bell opened their new exhibition about the unchecked power Facebook and the other big tech companies wield.

Internet Giants: Masters of the Universe, at Birmingham's Ikon Gallery until 10 June, marks the 40th year of collaboration between Langlands and Bell. It is an arresting ensemble of installations and animations, prints and architectural models.
