As retail titans Walmart and Amazon unveil new tech at CES, the competition heats up with a focus on AI-driven personal shopping experiences. Walmart pitches itself as a potential AI concierge, while Amazon furthers its 'Buy with Prime' service across more platforms.

Amidst strategic cuts, with Amazon streamlining by shedding jobs and projects, Walmart contrasts with expansion, opening new stores, and embracing eCommerce. Amazon's Prime Video and other divisions face downsizing after a thorough business review, signaling a pivot towards more impactful initiatives.

On the digital forefront, Walmart invests in artificial intelligence and robotics, enhancing operational efficiency and the customer shopping journey. Amazon, not to be outdone, integrates AI to personalize the online retail experience, announcing a novel collaboration with Salesforce Commerce Cloud.

Both giants are also vying for a slice of the healthcare pie, eyeing dominance with affordable services and leveraging their extensive networks. As these behemoths adopt AI and other technologies, the race for consumer attention in a merged physical-digital retail world intensifies.
