Welcome, dear readers. Are we living through another tech bubble—and is quantum computing the next hype train? That’s today’s question. In this piece, we’ll unpack what’s real, what’s froth, and what the data suggests about AI, datacenters, and the new “quantum rescue” narrative. Stick with us for a grounded tour: you’ll learn how to spot bubble logic, read datacenter forecasts, and avoid confusing wishful thinking with physics.
AI bubble..
The AI boom looks stretched: profits lag, costs rise, and infrastructure bets are massive. Even bullish banks are now flagging downside risks if monetization stalls, with datacenter buildouts exposed to any slowdown in AI demand . Meanwhile, a fresh storyline says quantum computing will “fix” AI’s limits—yet practical algorithms and timelines remain narrow and uncertain, making it a risky lifeboat for investors . The smart move is to separate engineering facts (compute, power, algorithms) from narratives (inevitable AGI, exponential returns). If we’re careful, we can capture genuine productivity gains while limiting waste, emissions, and future disillusion.
One Everyday Analogy
Think of AI like a new highway. We’ve poured concrete (chips, datacenters), but toll booths (business models) still barely collect. Quantum computing is the promise of flying cars to skip the traffic—exciting, but we don’t have the engines, fuel, or safety rules yet.
A 60-Second Try-It Step
Open a note and write three lists for any hyped tech:
- Inputs: energy, hardware, people.
- Outputs: revenue, time saved, accuracy.
- Bottlenecks: physics, cost, regulation. If outputs don’t clearly beat inputs (today, not “someday”), be skeptical.
3 Short FAQs
- Is AI demand still growing? Yes—but forecasts now include explicit downside if returns disappoint .
- Will quantum turbo-charge AI soon? Unclear. Hardware is hard; useful algorithms are scarcer than headlines imply .
- Does this mean avoid AI entirely? No. Focus on narrow, verifiable use-cases with measurable ROI.
What are the hard numbers saying right now?
Even upbeat analysts now place AI inside scenario bands, not destiny. Research cited by The Register reports:
- Global datacenter capacity ~62 GW today.
- Base case ~92 GW by 2027 (≈17% CAGR), with 14–20% scenario bounds.
- AI’s share of capacity rises from ~13% in early 2023 to ~28% by 2027.
- Power use for datacenters could reach 3–4% of global electricity by 2030, with ~60% of the extra power likely from gas, adding ~215–220 Mt CO₂e .
Here’s a quick, clean table you can reuse in your notes:
| Metric | Today | 2027 Base | Scenario Range | Notes |
|---|---|---|---|---|
| Global capacity | ~62 GW | ~92 GW | 14–20% CAGR | AI expansion drives absolute growth |
| AI share of capacity | ~13% | ~28% | — | Faster growth vs. cloud/traditional |
| Power share (global) | ~1–2% (2023) | — | 3–4% (2030) | Large energy + emissions footprint |
| Power mix (incremental) | — | — | ~40% renewables, ~60% gas | ~215–220 Mt CO₂e by 2030 |

A simple growth check you can run
To sanity-check capacity forecasts, use compound growth:
Plugging rough values:
That lands close to the base-case 2027 figure—good sign the math and the claim align .
Why do many AI deployments still look shaky?
Reports and analyses collected by Will Lockett point to a tough pattern: many pilots fail to deliver clear productivity or profit; when they work, they’re narrow and back-office, with modest gains. He also highlights developer slowdowns from error-prone code assistance and growing worker workload without matching output, painting a picture of limited near-term ROI for broad, generative AI rollouts .
What this means for you: progress is real, but generalized, plug-and-play productivity miracles remain rare. Evaluate specific tasks, not “AI” in the abstract.
Is quantum computing the “fix” for AI’s limits?
The tempting story: qubits bring exponential parallelism, slashing training time and unlocking human-level intelligence. The reality:
- Hardware: universal, fault-tolerant machines remain years away; operating them is exquisitely hard.
- Algorithms: quantum speedups require special algorithms; many practical AI tasks don’t map cleanly. The pool of known, broadly useful algorithms is small, and chemistry/ML gains are unproven at scale .
Here’s a quick comparison you can bookmark:
| Claim | What the sources say | Implication |
|---|---|---|
| “Quantum will accelerate any AI workload.” | Speedups need specific algorithms; many AI math kernels may not benefit. | Expect niche wins, not universal upgrades :contentReference[oaicite:11]{index=11}. |
| “Quantum is imminent.” | Timelines remain uncertain; fault-tolerant systems are not widely available. | Plan for years, not months, of R&D risk :contentReference[oaicite:12]{index=12}. |
| “Quantum rescues AI economics.” | No evidence of broad cost/performance relief for today’s AI workloads. | Don’t base datacenter capex on speculative quantum gains :contentReference[oaicite:13]{index=13}. |
What’s really driving the datacenter rush—and why does it matter?
Fear of missing out is real. Goldman’s quoted view: hyperscalers are “playing offense and defense,” accelerating spend even as monetization remains uncertain. If demand underperforms, the datacenter surge could overshoot, pulling back investment and denting adjacent sectors (chips, power generation, real estate) .
The energy and emissions angle
Large AI racks may reach ~600 kW per rack by 2027—akin to ~500 U.S. homes—shifting grid planning and siting constraints. With ~60% of incremental power likely from gas this decade, emissions footprints grow unless policy, grid upgrades, and efficiency breakthroughs arrive together .
A compact rule of thumb:
Where EF is the grid’s emissions factor. Lowering any factor lowers the footprint.
How do we invest attention (and money) more wisely?
- Target narrow tasks with measurable KPIs: accuracy, time saved, error rate.
- Favor data quality and workflow redesign over maximal model size.
- Stress-test economics with real energy and hardware costs, not averages.
- Treat quantum as research, not a budget line for near-term AI ROI.
And yes, look for honest red-teams: people free to say “this doesn’t work yet.”
What if the bubble does deflate?
Popping doesn’t mean “AI is useless.” It means expectations reset. We keep what works—translation, summarization, retrieval-augmented workflows, specialized copilots—and we right-size infrastructure. The goal is resilient progress, not cliff-edge boom-bust cycles.
Will Lockett’s critique warns that a pivot to quantum hype could just delay the reckoning. Better to acknowledge limits now and build patiently, with physics and balance sheets in view .
Conclusion: Can we choose signal over noise?
We can. Let’s make space for evidence, not just excitement. AI is valuable where tasks are well-defined and data is disciplined. Datacenters are vital, but they’re not free—in money, power, or carbon. Quantum computing is fascinating, yet it’s research-grade for most AI problems. If we align investment with what works today—while funding real science for tomorrow—we get compounding value instead of compounding disappointment.
