Amazon shelves Blue Jay warehouse robot

Amazon made a lot of noise last October when it unveiled Blue Jay, a multi-armed warehouse robot built to speed up same-day deliveries. Just months later, the company quietly ended the program.

The robot's core technology will live on in other projects. Still, Blue Jay itself is done.

That sudden shift raises an important question. If one of the world's most advanced logistics companies cannot make a high-profile robot work at scale, what does that say about the future of artificial intelligence (AI) in the real world?
