This book from Jenny Odell is about a big, ontological question: What is time? She builds on her recent book How to Do Nothing — an inspiring, if unsettling, push against the “attention economy” — by pointing to ways we commodify time. Pick through some broadly brushed assumptions, and this accusation rings true. You’ve heard “time is money.” You’ve seen people use $900 cellphones to upload anything memorable to websites for sale. Unfortunately, Saving Time gets confusing, with long runs of hard-to-follow ideas, and it randomly includes poorly printed photography. Still, Odell’s premise deserves, ahem, attention, and the book’s slog through different perspectives on the experience of time does yield hope for a more time-honoring clock.
