另一挑战在于数据。训练语言模型可依赖海量网络文本，但机器人需要物理世界的场景数据。例如训练机器人完成开门动作，可能需要上百甚至上千次重复，从每次失败中不断调整算法。
双重缺陷叠加产生灾难性影响。以审阅GitHub拉取请求为例，正常缓存本可节省九成重复计算成本，但因系统缺陷用户始终按全额付费，实际支出激增十至二十倍。

Сообщается о трех пострадавших при сходе состава с сотнями пассажиров в России08:44
This wasn't Randy Bennett's best team, nor his worst. But it was his last in Moraga, as he's headed to Arizona State. The Gaels knocked off Gonzaga in the pair's final meeting as conference rivals, but they also fell to Santa Clara twice. Saint Mary's often finds itself in one of these 5-12, 6-11, 7-10 games that can lean either direction. And, more often than not, the slow pace and great ball movement lead to competitive matchups. Not so much this time: Texas A&M sprinted out to a 9-0 lead and never trailed. Between 18 turnovers and multiple extended scoring droughts, a loss like this still hurts a bit, even more so with it being Bennett's final game.
