The weirdest stuff we saw at CES 2022: John Deere's self-driving tractor, robot masseuses

LAS VEGAS – CES 2022 lacked its usual crowds and some of its headline acts, but the gadget show that returned to this city after the pandemic forced it to go online-only last year retained a certain exuberant weirdness. You can count on the technology industry to supply more possibilities than the market will necessarily demand. And you can expect many of those to surface at the Arlington, Virginia-based Consumer Technology Association's annual gathering, even if they never make it to any store. The big-name vendors that scrapped plans to exhibit in person over fear of the aggressively-spreading omicron variant still had paid-up show-floor space. That led to such minimalist workarounds as LG's "Life's Good Lounge," an expanse of plywood adorned with QR codes for attendees to scan to get more information about products they could not see or touch.
