Folding towels is not the kind of work that usually attracts serious venture money. But according to Business Insider, several heavily funded robotics startups have converged on exactly that task as the first thing their machines should learn to do.

Business Insider reports that Sunday Robotics, Weave, and 1X are all starting with the same core job — laundry — and describes it as the industry's favorite gateway into the home. The piece is framed around why billion-dollar robotics companies have become, in its words, obsessed with folding laundry.

It is worth being clear about what the reporting does and doesn't say. The common thread is the starting point, not the finish line: laundry is presented as an entry task, a way in, rather than the whole product these companies intend to sell.

Still, the choice is telling. Laundry sits at the awkward intersection of chores people genuinely want to hand off and problems that are hard for machines. Clothes have no fixed shape. A shirt looks different every time it lands in a basket. A robot that can reliably pick up, orient, and fold a crumpled piece of fabric has solved something that a factory arm bolted to a floor never has to face.

That also makes laundry a useful public scoreboard. Anyone can watch a video of a robot folding a shirt and judge for themselves whether it worked, which is not true of most claims in robotics.

Why it matters: the household chore these startups pick first is a signal of how close — or how far — general-purpose home robots really are from being useful in an ordinary house.
