The significance of this spending extends well beyond the technology sector. As
S&P notes, it is becoming one of the defining forces shaping
the global economic outlook, influencing manufacturing activity, trade flows, productivity expectations and labour-market planning.
AI also brings risks beyond the investment case. OpenAI’s Sam Altman
and SpaceX’s Elon Musk have supported a
call by Anthropic’s Dario Amodei for a slowdown in the pace of AI development. He cites the loss of control over AI systems, their misuse in cyberattacks or bioterrorism and serious economic disruption.
The surge in AI-related corporate bond issuance also poses risks to bond and credit markets. Higher borrowing costs can filter through to individuals via inflation, tougher mortgage markets, higher credit-card rates and potentially weaker pension
portfolios.
The central question for investors, therefore, is not simply whether AI spending will generate returns above the cost of capital. It is whether AI can benefit all levels of society and improve human existence without causing irreversible environmental damage, weakening competition
and privacy or creating greater inequality.
