The opacity of AI-sector financing compounds these vulnerabilities. Hyperscalers, chip makers and AI labs are linked through a complex web of private arrangements. The most prominent is circular financing: chip makers and hyperscalers take equity stakes in AI labs or neocloud providers, who in turn commit to multi-year purchases of chips or computing power. Data centre construction is increasingly outsourced to third parties that lease facilities back to hyperscalers on long-dated contracts with embedded exit clauses. The terms of such deals are typically poorly disclosed, with risks of the same asset being pledged multiple times. Together, such arrangements account for a sizeable share of sector-wide financing and forward revenue (Graph 13.C). A sharp repricing of equity risk could prompt a reassessment of corporate credit risk and lead to tighter credit conditions more broadly.1 Indeed, broad indices of credit spreads tend to correlate negatively with stock market returns (Graph 14.A), more so for the high-yield than the investment grade segment. While large, synchronised corrections in both markets are rare, there are notable precedents such as the Great Financial Crisis and the March 2020 dash for cash episode. A repricing of risk this time, whether triggered by higher interest rates or an AI bust, has the potential to be similarly disruptive by triggering a corporate credit freeze with wider implications for aggregate investment. Any tightening in credit conditions could expose existing vulnerabilities in the less transparent private credit space, whose reach has expanded among middle market and small firms (Graph 14.B). Signs of stress are already visible: direct lending funds catering to retail investors have faced mounting redemption requests, forcing some to liquidate assets and return capital despite having no contractual obligation...

em: its understandable why artists are generally polarized against ai. The people making ai have a fairly good understanding of the types of tools programmers want and basically no clue how to make good tools for artists. llms support a variety of levels of coding automation, you can use it for review/analysis of your code, micromanage and direct every action, let it design entire programs by itself. For art it seems like you only really have prompt -> complete image, which yields the worst results for programming.

srrrse: It's actually a great time to care about the craft. I don't know if people realise this but you can write whatever into the prompt box. You can use the AI to get the function just right instead of making it generate crap as fast as possible. Laurie Voss: I have always been the kind of developer who only cares about outcomes. Give me the tool, the framework, the head start. I just want my website. A totally different kind of developer exists who carers about the *craft*. Getting that function just right. Those devs are in pain right now.
