Big Tech companies such as Google, Amazon and Microsoft are moving into AI healthcare services in a big way. But can we trust private, for-profit, companies to use our data properly? Prof Allyson Pollock, director of the Newcastle University Centre for Excellence in Regulatory Science in the UK, tell the BBC's Ed Butler she is alarmed at the rate healthcare services are being privatised in the country. And Nicholson Price, Professor at the University of Michigan School of Law in the US, warns that the stakes are different when tech companies collect healthcare than say marketing information. But Dr Robert Wachter, Professor and Chair of the Department of Medicine at the University of California, San Francisco, says that though these concerns are real, it may be a price we have to pay for better healthcare in the future.
