Prioritizing Memory Efficiency and Infrastructure Over Regulatory Anxiety

Original Title: 20VC: "Anti-Data Centres is a Chinese Psyop" | How Many Planned Data Centers Will Actually Get Built? | Is Energy AI's Biggest Bottleneck? With Thomas Sohmers, Co-Founder @ Positron

The infrastructure of AI is currently suffering from a crisis of perception. While public discourse is dominated by fears of data center energy consumption and frontier safety, these concerns often mask deeper systemic shifts in compute architecture and economic incentives. Thomas Sohmers, co-founder of Positron AI, argues that the real bottleneck is not just energy, but the misallocation of capital and the regulatory capture of technological progress. For leaders and investors, the advantage lies in looking past the anti-data center sentiment, which Sohmers characterizes as a strategic distraction, and understanding the shift from compute-bound training to memory-bound inference. Those who grasp the economics of KV caching and the necessity of vertical integration will be the ones to capitalize on the next wave of AI productivity, while others remain stalled by outdated regulatory frameworks and surface-level anxieties.

The Hidden Cost of Frontier Pacing

The conversation around pacing the frontier is often framed as a safety imperative, but Sohmers suggests that the strategic incentives are far more terrestrial. While some leaders may genuinely believe in the risks of rapid advancement, the push for heavy regulation creates a moat that favors incumbents. By inviting government oversight, large labs may inadvertently be creating a bureaucratic trap that slows down the entire ecosystem, potentially leading to a pre-enlightenment state of technological stagnation.

This creates a paradox: the more the West slows down through regulation, the more it cedes the long-term advantage to regimes like China, which are aggressively building out infrastructure without the same policy constraints. The non-obvious consequence here is that safety measures could paradoxically result in the centralization of power, effectively squandering the democratic potential of the technology to a select group of bureaucrats.

Why the Obvious Fix Makes Things Worse

Conventional wisdom views the energy demands of data centers as an existential threat to be mitigated. Sohmers argues this is a failure of systems thinking. Data centers are being targeted based on false premises, such as water usage comparisons that ignore the efficiency of closed-loop cooling systems. The systemic danger is that local political pushback forces these facilities to move, but it does not stop the underlying demand.

The system simply routes around the restriction. When Republican governors and local politicians retreat from pro-growth stances to appease anti-data center bases, they are essentially opting out of the infrastructure race. The downstream effect is not a greener world, but a less competitive one where the economic benefits of increased energy generation, which would actually lower costs for consumers, are forfeited.

The KV Cache: The Real Economic Lever

While the public focuses on bigger models, the true battleground for profitability is the memory-bound nature of inference. Because generating tokens is an auto-regressive process, it cannot be parallelized like training. This is where KV (Key-Value) caching becomes the dark art of modern AI infrastructure.

The hidden dynamic here is that 96% of tokens in complex agentic workflows are cached. This makes the ability to store and retrieve these caches more important than raw compute speed. Companies that master the tiering of this memory, keeping active sessions in expensive accelerator memory while offloading dormant ones to host memory or flash storage, will see massive margin expansion. Most observers miss this, assuming that AI is a burn cash business, when in reality, the high margins are hidden in the efficiency of these cached reads.

The 18-Month Payoff: Why Local Intelligence Drives Cloud Growth

A common, yet potentially flawed, assumption is that the rise of on-device, small-model AI will cannibalize the cloud. Sohmers posits the opposite: local AI acts as a multiplier. When a device has constant, low-latency access to a user’s data, it does not replace the cloud; it acts as a filter that triggers more frequent, high-value requests to frontier models. The bottleneck today is human decision-making. Once we trust local agents to autonomously prompt the cloud, the volume of tokens processed by frontier models will likely increase by orders of magnitude.

Key Action Items

  • Audit your infrastructure for cache efficiency: Evaluate whether your current stack is optimizing for compute or memory-bound inference. This is a technical investment that pays off in lower per-token costs over the next 6-12 months.
  • Prioritize long-context recall over raw parameter counts: Stop chasing the largest model metric. Focus on benchmarks like needle-in-a-haystack to ensure your model can actually utilize its context window effectively.
  • Decouple from frontier regulatory anxiety: Don't base your roadmap on the assumption that frontier models will be paused. Plan for a future where access to high-intelligence models remains a competitive necessity, regardless of political headwinds.
  • Invest in agentic workflows now: The next wave of value is not just in chat, but in autonomous agents that bridge the gap between local data and cloud intelligence. Over the next 18 months, prioritize tools that allow for this hand-off.
  • Look past the Energy Bottleneck narrative: Recognize that energy constraints are often economic and regulatory, not physical. Seek out regions or partners that are actively expanding generation capacity rather than those caught in the anti-data center political loop.
