So, Amazon deployed the latest thinking in deep learning, computer vision data analytics and AI algorithms to convert a simple visit to the shops into a complex interaction of object and person recognition.
The system works like an autonomous vehicle that segments what it sees into pixels and builds a map in its own mind about what's going on, making weighted decisions about what it "sees" - identifying objects, placing them in the store and attempting to predict movement and recording completed actions.
All these different feeds are brought together in a process called sensor fusion to form a single model of the shopper's activity, attaching significance to each action and its relevance to purchases.
The technology may have been developed and pioneered by Amazon, but artificial intelligence is coming to a high street near you. According to research group Gartner, some 77 per cent of retailers are putting AI in place this year in order to boost the customer experience, some driven by Amazon's ground-breaking innovations.
Dr Amirhosseini said the typical fear - of robots taking human jobs - need not play out.
He said, "The rapid adoption of ATMS from 1980 to 2000 increased the number of bank teller jobs throughout that period because ATMs lowered the cost of opening new branches. This led to banks hiring more bank related workers. But the job description changed. They began to handle more customer relations as their more routine tasks were being automated."
"So, the process of automation may disrupt industries but ultimately it will create new and better jobs and grow the economy. Cognitive skills have become more important than physical activity, because of the AI revolution."
The irony stands therefore that Amazon, which has taken the lion's share of retail business during lockdown and has been seen as the greatest threat to the viability of the high street may be leading the march back to local shopping.
