海外TECH	Engadget	Hitting the Books: Why AI needs regulation and how we can do it	https://www.engadget.com/hitting-the-books-containing-big-tech-tom-kemp-it-rev-ai-regulation-143014628.html?src=rss	Hitting the Books Why AI needs regulation and how we can do itThe burgeoning AI industry has barrelled clean past the move fast portion of its development right into the part where we break things ーlike society Since the release of ChatGPT last November generative AI systems have taken the digital world by storm finding use in everything from machine coding and industrial applications to game design and virtual entertainment It s also quickly been adopted for illicit purposes like scaling spam email operations and creating deepfakes nbsp That s one technological genie we re never getting back in its bottle so we d better get working on regulating it argues Silicon Valley based author entrepreneur investor and policy advisor Tom Kemp in his new book Containing Big Tech How to Protect Our Civil Rights Economy and Democracy In the excerpt below Kemp explains what form that regulation might take and what its enforcement would mean for consumers nbsp Fast Company PressExcerpt from Containing Big Tech How to Protect Our Civil Rights Economy and Democracy IT Rev August by Tom Kemp Road map to contain AIPandora in the Greek myth brought powerful gifts but also unleashed mighty plagues and evils So likewise with AI we need to harness its benefits but keep the potential harms that AI can cause to humans inside the proverbial Pandora s box When Dr Timnit Gebru founder of the Distributed Artificial Intelligence Research Institute DAIR was asked by the New York Times regarding how to confront AI bias she answered in part with this “We need to have principles and standards and governing bodies and people voting on things and algorithms being checked something similar to the FDA Food and Drug Administration So for me it s not as simple as creating a more diverse data set and things are fixed She s right First and foremost we need regulation AI is a new game and it needs rules and referees She suggested we need an FDA equivalent for AI In effect both the AAA and ADPPA call for the FTC to act in that role but instead of drug submissions and approval being handled by the FDA Big Tech and others should send their AI impact assessments to the FTC for AI systems These assessments would be for AI systems in high impact areas such as housing employment and credit helping us better address digital redlining Thus these bills foster needed accountability and transparency for consumers In the fall of the Biden Administration s Office of Science and Technology Policy OSTP even proposed a “Blueprint for an AI Bill of Rights Protections include the right to “know that an automated system is being used and understand how and why it contributes to outcomes that impact you This is a great idea and could be incorporated into the rulemaking responsibilities that the FTC would have if the AAA or ADPPA passed The point is that AI should not be a complete black box to consumers and consumers should have rights to know and objectーmuch like they should have with collecting and processing their personal data Furthermore consumers should have a right of private action if AI based systems harm them And websites with a significant amount of AI generated text and images should have the equivalent of a food nutrition label to let us know what AI generated content is versus human generated We also need AI certifications For instance the finance industry has accredited certified public accountants CPAs and certified financial audits and statements so we should have the equivalent for AI And we need codes of conduct in the use of AI as well as industry standards For example the International Organization for Standardization ISO publishes quality management standards that organizations can adhere to for cybersecurity food safety and so on Fortunately a working group with ISO has begun developing a new standard for AI risk management And in another positive development the National Institute of Standards and Technology NIST released its initial framework for AI risk management in January We must remind companies to have more diverse and inclusive design teams building AI As Olga Russakovsky assistant professor in the Department of Computer Science at Princeton University said “There are a lot of opportunities to diversify this pool of people building AI systems and as diversity grows the AI systems themselves will become less biased As regulators and lawmakers delve into antitrust issues concerning Big Tech firms AI should not be overlooked To paraphrase Wayne Gretzky regulators need to skate where the puck is going not where it has been AI is where the puck is going in technology Therefore acquisitions of AI companies by Big Tech companies should be more closely scrutinized In addition the government should consider mandating open intellectual property for AI For example this could be modeled on the federal consent decree with Bell that required Bell to license all its patents royalty free to other businesses This led to incredible innovations such as the transistor the solar cell and the laser It is not healthy for our economy to have the future of technology concentrated in a few firms hands Finally our society and economy need to better prepare ourselves for the impact of AI on displacing workers through automation Yes we need to prepare our citizens with better education and training for new jobs in an AI world But we need to be smart about this as we can t say let s retrain everyone to be software developers because only some have that skill or interest Note also that AI is increasingly being built to automate the development of software programs so even knowing what software skills should be taught in an AI world is critical As economist Joseph E Stiglitz pointed out we have had problems managing smaller scale changes in tech and globalization that have led to polarization and a weakening of our democracy and AI s changes are more profound Thus we must prepare ourselves for that and ensure that AI is a net positive for society Given that Big Tech is leading the charge on AI ensuring its effects are positive should start with them AI is incredibly powerful and Big Tech is “all in with AI but AI is fraught with risks if bias is introduced or if it s built to exploit And as I documented Big Tech has had issues with its use of AI This means that not only are the depth and breadth of the collection of our sensitive data a threat but how Big Tech uses AI to process this data and to make automated decisions is also threatening Thus in the same way we need to contain digital surveillance we must also ensure Big Tech is not opening Pandora s box with AI
