Kevin O'Leary, venture capitalist and Shark Tank co-host, predicts that AI and blockchain will drive a major transformation in business operations. In a recent video, O'Leary explained how AI could autonomously handle retail purchases, while blockchain would manage payments. He illustrated a scenario where a customer could order a coffee via voice command, with AI determining the nearest café and blockchain processing the payment instantly. Despite the potential, O'Leary noted the current limitations of blockchain solutions like Ethereum, which struggle with high transaction volumes due to linear processing. He highlighted Directed Acyclic Graphs (DAGs) as a promising alternative, with platforms like Hedera and Nano offering scalable solutions. O'Leary is on the lookout for a project that can efficiently handle millions of transactions daily, a necessity for large retailers like Walmart and Target.
