Gary Marcus 引用报告质疑 AI 占 GDP 9% 的投资逻辑

no Trevor Noren @trevornoren WSJ: "Is it plausible that Americans will spend as much of their income on this one technology as they do on food? Roughly twice what the nation pays for all forms of energy or all computers and software? Seven times what consumers spend on phone, streaming, and internet services combined? You should be skeptical. Even the most transformative inventions eventually run into the law of diminishing returns: each additional dollar a user spends yields less additional productivity (or enjoyment) than the last. That imposes a natural ceiling. The question, of course, is where that ceiling is. Whether or not you think 9% of GDP is right, you have to care, because this figure isn’t some fever dream: it is implicit in the dollars that investors and companies are committing right now." As I dissect in my report on "The AI Trade" ( sageroadresearch.com/collections/re… ), it's also important to recognize that consumers are unlikely to account for much of that "9% of GDP": "The vast majority of consumers don’t spend money on AI, with only 3% of US households paying for an AI service as of March, according to Bank of America data. We’re doubtful that payment rate will increase significantly anytime soon. That’s in large part because AI is primarily used by consumers as a search engine and for the entire history of the internet, search engines have been accessible for free. According to McKinsey, 50% of US consumers now use AI search. AI platforms are now taking 15 to 20% of informational query volume, according to DigitalApplied. If anything, consumer AI use is a threat to search-driven revenue. AI search reduces ad interaction, with 20 to 50% of click-through traffic at risk as AI search results “capture decisions earlier in the journey,” according to McKinsey projections. Enterprises, not consumers, are the great short- and long-term hope for AI profitability, or as Goldman Sachs’ equity research team summed up in May: “Successful enterprise AI adoption will drive the economics for the entire supply chain.” The enterprise capital required to subsidize the AI buildout will have to come from savings generated via labor replacement or growth driven by increased productivity or a combination of both. Significant and persistent hurdles remain. To again quote the report: "In December, we warned that market participants were overestimating GenAI’s strengths and trajectory of improvement and underestimating its persistent weaknesses, which would hold back enterprise adoption. We won’t retread all of the evidence we presented to support that conviction, but to sum up the basic concerns: Models remain error prone, which constrains utility. Their contextual understanding is limited and ivory-tower prognostications about job displacement to come neglect the contextual understanding required to execute even low-level tasks across sectors. Finally, most legacy companies will be unwilling or unprepared to tear down existing operations enough to mitigate these challenges and maximize AI’s potential."
