The price per token of AI intelligence has been falling rapidly for the past 5 years due to algorithmic improvements, but physical supply constraints are expected to reverse this trend.

Shifting to the infrastructure dimension, Andreessen offers a detailed supply-chain taxonomy of AI's physical constraints. At the bottom: energy production, where permitting and generation capacity are already binding. Above that: physical data centers, where turbines are sold out four years in advance and transformers are unavailable — one major hyperscaler is apparently milling its own turbine blades [1] — Marc Andreessen "Every layer of the AI infrastructure stack is constrained: energy production, physical data centers, turbines (sold out 4 years), transform…" 20:10 . Cooling systems, large HVAC units, and water cooling are similarly constrained. Inside the data center: NVIDIA GPUs are in tight supply, memory chips face acute shortages with prices spiking and stocks following. And at the raw materials layer: rare earth minerals for advanced semiconductors are becoming bottlenecks. The practical consequence, Andreessen says, is that consumers and businesses are accessing dumber versions of AI than would exist if the supply chain were liberated — models are less capable than they could be because companies don't have the chips and power to train better ones. Meanwhile, the 5-year trend of rapidly declining AI costs is running up against these physical limits, and Andreessen suggests the price of intelligence may actually start rising.
Every layer of the AI infrastructure stack is constrained: energy production, physical data centers, turbines (sold out 4 years), transformers, HVAC cooling, GPUs, memory chips, and rare earth materials. The consequence is that the AI products available today are dumber than they need to be — not because of algorithm limits but because there aren't enough chips and power to train better models.
Andreessen notes that turbines needed for data center power generation are sold out approximately 4 years in advance, exemplifying supply chain bottlenecks on AI infrastructure.
The US is completely dependent on Taiwanese semiconductor fabs for advanced AI chips. But that dependency paradoxically makes Taiwan more dangerous, not safer — it turns the island into an irresistible prize for China. Andreessen argues Taiwan is 'almost too important for its own good,' and this is the clearest national security argument for US chip reindustrialization.
Sam's initial MVP was coded in approximately one week using ChatGPT voice mode and copy-pasting code, with no prior technical experience.
Sam argues Discord is 10x better than email for building relationships with younger users who rarely check their inbox.
Sam's monthly operating costs include Cursor ($200), AI image generation ($100), AI video generation ($200), hosting ($100), email marketing ($80), and AI compute ($300–$500).
Sam recommends copying days of Discord chat history into ChatGPT and prompting it to list recurring pain points as a fast, free market research technique.
Bhanu and his team built approximately 50 free tools to attract search traffic, each linked back to SiteGPT.
With AI coding tools like Cursor, Bhanu can now create a new free marketing tool in less than 5 minutes by referencing existing tools.
Bhanu filters Ahrefs keyword results to show only those with a keyword difficulty below 10, making them realistic ranking targets for any decent website.
Bhanu sets a minimum search volume of 1,000 monthly searches when selecting keywords to target with free tools.
PropGPT averaged 20 downloads per day right after launching on the App Store through influencer marketing.
