Artificial Intelligence Masterclass
Episode Title: AI isn't a bubble
Date: December 23, 2025
Host: David Shapiro (AI Masterclass)
Episode Overview
In this episode, David Shapiro offers a thought-provoking and refreshingly contrarian analysis of the current state of artificial intelligence (AI) economics. Addressing concerns that AI is the next big financial bubble, he explains why the “bubble” narrative misunderstands both the structure of the AI boom and its underlying technological drivers. Drawing connections to past industrial revolutions, Shapiro substantiates his pragmatic optimism about AI’s future and debunks misconceptions with data and historical context.
Key Discussion Points & Insights
1. AI as a “Bubble”: Consensus and Contrarianism
- Context: Social and financial media are saturated with comparisons of AI to past financial bubbles (Dot-Com bust, Tulip Mania).
- Host’s Stance:
“I'm not saying that there aren't structural problems... I'm just saying it's not that simple.” (02:07)
- Core Argument:
Today’s AI boom has critical structural differences compared to traditional bubbles—it runs on profit over promises.
2. Structural Differences: Dot-Com Bubble vs. AI Boom
- Profit Foundations:
- The Dot-Com Bubble featured companies with valuation based solely on potential ("eyeballs"), leading to PE ratios >100.
- AI Today: The major players (Microsoft, Google, Meta, Amazon) generated $300B+ in operating cash flow last year.
“Valuations are based on massive cash flow… This is a very, very big structural difference between then and now.” (03:40)
- Current PE ratio for tech giants is about 30×, still high but not “insane.”
- Capital Expenditure (CapEx) and Debt:
Massive spending is viewed as rational investment to capture more future revenue.“If their operating revenue is already $300 billion and they're basically saying, ‘Hey, we can spend $600 billion to build out and capture more revenue,’ you know, that kind of makes sense.” (04:48)
3. Investment Phases: Industrial Revolution Patterns
- Carlota Perez Framework:
“Installation phase” (infrastructure buildout, overspending, ‘bubble’ perception) followed by “deployment phase” (widespread adoption, utility).- 2027–2032 projected as the “deployment phase” for AI. (06:02)
- Tech Hype Cycle:
“Now it's the long slope of enlightenment where we all kind of have a more realistic worldview as to what this thing is.” (07:08)
- The “trough of disillusionment” does not equate to a collapse but a natural, historical adjustment period before resurgence.
4. The J Curve and Productivity Lag
- Solo Paradox/J-Curve:
Initial costs in new general-purpose tech (e.g., AI) spike—retraining, restructuring, purchases—but productivity increases are delayed.- Example:
“You can see the computer age everywhere but in the productivity statistics.” —Robert Solow, 1987 (09:50)
- Example:
- Historical Adoption Lags:
- Steam Power: ~100 years
- Electricity: ~30 years
- Computers: ~20 years
- SaaS: ~10 years
- AI (projected): Just 2–5 years (10:51)
- Acceleration:
This compression is due to prior infrastructural readiness—AI rides on SaaS and cloud, enabling faster adoption.
5. Demand Pull vs. Supply Push
- Dot-Com:
- “If you build it, they will come.” Speculative supply-sided buildup led to dark, unused infrastructure. (13:20)
- AI Today:
- Unmet, Real Demand:
“Please stop asking for GPUs, we're out of stock... Google and Microsoft are capacity constrained, turning away high end compute customers.” (15:10)
- Even free-tier constraints (Claude/Anthropic) signal consumer and enterprise demand ahead of supply.
“The world wants more AI than we have. And the fact that... it hasn't even gotten good yet tells you that this is a demand-side problem, not a supply-side problem.” (16:44)
- Unmet, Real Demand:
6. The GPU Market: Productive Capital, Not Speculation
- GPUs vs. Tulips:
- “GPUs are money printers, not tulips.”
- Tulips: Zero-yield, pure speculation.
- GPUs: Capital assets, provide yield, productive use (rentable, immediate revenue generation). (20:11)
- “GPUs are money printers, not tulips.”
- Economics:
- Example: Nvidia H100 GPU costs $25K–$30K, generates $13K/year at 60% utilization—payback in ~2 years.
“This is a standard industrial equipment payback cycle, similar to a CNC machine or a commercial truck.” (21:12)
- Main Risk Is Obsolescence, Not Zero Value:
- Hardware becoming obsolete (e.g., when Blackwell B200 launches) means creative destruction, not speculative implosion.
“The risk isn’t a bubble, it’s rapid obsolescence.” (22:35)
7. Measurement Challenges & Productivity Data
- GDP & Productivity Measurement:
- Early in tech cycles, gains are “hidden” due to classification errors (Opex vs. Capex, pricing deflation).
- AI likely undercounted in GDP/productivity stats—paralleling prior computer/software eras.
“People are like, oh well, AI hasn't hit GDP yet. It's partly a methodological error and it's partly a classification error.” (25:18)
- Expect official metrics to spike when R&D and training expenditures are reclassified as capital investment.
8. Contrasting Frameworks: Bubble vs. Industrial Revolution Model
- Bubble Narrative:
- Driven by speculation/mania
- Zero-yield core asset
- Theoretical demand (supply-push)
- Risks: The “greater fool” disappears
- Industrial Revolution Narrative:
- General purpose, productive technology
- Real, unmet, demand-pull
- Key risk is obsolescence and valuation, not illusory value
“A GPU going obsolete is not the same as a tulip losing its value. It is very fundamentally structurally different.” (28:01)
Notable Quotes & Memorable Moments
- “Microsoft, Google, Meta, Amazon generated over $300 billion in operating cash flow last year. That's not nothing.” (03:30)
- “If their operating revenue is already $300 billion and they're basically saying, ‘Hey, we can spend $600 billion to build out and capture more revenue,’ you know, that kind of makes sense.” (04:48)
- “You can see the computer age everywhere but in the productivity statistics.” —Robert Solow, 1987 (09:58)
- “The world wants more AI than we have. And... it hasn't even gotten good yet tells you this is a demand side problem, not a supply side problem.” (16:44)
- “GPUs are money printers, not tulips.” (20:11)
- “This is a standard industrial equipment payback cycle, similar to a CNC machine or a commercial truck.” (21:12)
- “The risk isn't a bubble, it’s rapid obsolescence... but... they're still going to be money printers while they're working.” (22:35)
- “People are like, oh well, AI hasn't hit GDP yet. It's partly a methodological error and it's partly a classification error.” (25:18)
- “A GPU going obsolete is not the same as a tulip losing its value. It is very fundamentally structurally different.” (28:01)
- “This is not just the same as a tech cycle. This is much more fundamentally structural, like the Internet itself, like the PC itself, like electricity itself.” (29:00)

Conclusion
David Shapiro systematically challenges the “AI is a bubble” narrative, framing the extraordinary investment, fervor, and risk-taking as consistent with the trajectories of past industrial revolutions. The true risks are rapid hardware obsolescence and valuation adjustments, not a catastrophic implosion. With robust demand, productive capital cycles, and accelerating adoption, AI’s economic surge is rooted in pragmatic value creation and is fundamentally different from previous bubbles. For skeptics and believers alike, the takeaway is clear: AI is not just a repeat of past tech manias—it’s a structural transformation of unprecedented scale.
