#3454 Alternate Computing Paths

#3454 Consider the various alternate paths computing could have taken from 1960 onward

Below are ten plausible “branch points” where computing history since 1960 could have unfolded very differently. For each I note (1) the real-world fork in the road, (2) a credible alternate trajectory, and (3) likely ripple-effects on technology, business, and society.

#Divergence (Year ±)Alternate PathConsequences & Knock-on Effects
1Analog vs. Digital (early 1960s)Defense contractors double-down on high-precision analog computers instead of switching budgets to transistorized digitals.• Continued R-&-D in magnetic amplifiers, fluidic logic, optical correlators → “hybrid analog supercomputers” dominate scientific/AI workloads into the 1990s.
• Universities teach Laplace transforms & nonlinear control as programming.
• Moore’s-law-style scaling pressure shifts to nano-mechanical and optical precision, not lithography.
2Core Logic Wins (mid-1960s)Jay Forrester’s team extends ferrite-core memory into core-logic gates that stay economical, delaying silicon IC supremacy.• Machines are bulky but radiation-hard; spaceflight and military adopt them widely.
• Software culture optimizes for huge magnetic delays—favoring data-parallel, streaming languages a decade early.
3TTL vs. ECL Flip (late 1960s)Motorola’s emitter-coupled logic (ECL) stays cheap and power-efficient; DEC migrates PDP line to ECL.• High-speed (GHz-class) minicomputers appear in the 1970s; real-time digital signal processing matures earlier.
• Heat-density crises arrive by 1985 → liquid-cooling norm in desktops.
4“Personal” LISP Machines Win (1973-80)Xerox PARC and MIT spin-out companies successfully market <$5 k LISP workstations.• AI-first OS (dynamic, garbage-collected) becomes mainstream; C never dominates.
• Early web‐like hypertext grows around symbolic data rather than byte streams; semantic search appears two decades sooner.
5Dataflow/Transputer Momentum (late 1970s)Inmos’s transputer and MIT’s TAG languages secure defense funding; ANSI backs data-flow model as a standard.• Mass-market micro-parallel chips ship in PCs circa 1985; functional languages taught as CS 101.
• Manycore debugging tools mature, smoothing today’s heterogeneous GPU programming struggles.
6Fiber-Optic Logic (mid-1980s)Bell Labs commercializes low-threshold semiconductor lasers integrated with GaAs optical switches.• “Light-inside” CPUs clocked at tens of GHz appear by 1995; optical RAM cross-bar solves Von-Neumann bottleneck.
• Data centers concentrate on photonic wafers, delaying cloud adoption (bandwidth plentiful on-chip, scarce off-chip).
7Open OS Ascendant (1990-1993)AT&T releases UNIX SVR4 under a permissive license; Microsoft pivots to middleware only.• Open-source kernel/API stack becomes industry default—mobile ecosystems never fragment.
• Security model built around reproducible builds and signed source; fewer large-scale ransomware events.
8Network Computer Triumph (mid-1990s)Larry Ellison’s and Sun’s thin-client push aligns with a global 64 kbps ISDN rollout.• Local storage dwindles; SaaS pricing norms appear a decade earlier.
• Browser API evolves to first-class 3-D & voice; “edge AI” stalls until late-2010s when on-device chips resurge.
9Early Quantum-Annealing Boom (late 1990s)Japanese MEXT funds superconducting adiabatic computers; Sony releases a 64-qubit coaster-sized add-on for PlayStation 2.• Quantum‐inspired heuristic chips become standard co-processors for logistics and finance by 2005.
• Cryptography pivots sooner; post-quantum algorithms normalized before widespread e-commerce.
103-D IC First (2005)Intel’s ‘Tessera’‐style stacking process solves thermal vias, beating planar 14 nm.• Chip density grows vertically; smartphones reach laptop-level compute by 2010.
• Heat extraction technologies (microfluidic cooling, thermoelectrics) become consumer-grade industries.

Strategic Take-Aways & Modern Opportunities

  1. Resilient Alternatives – Many paths above favor robustness (radiation-hard core logic, optical interconnects). → Opportunity: revisit these ideas for space, defense, and harsh-environment edge AI.

  2. Parallel-First Cultures – Early dataflow or transputer victories show the cultural lock-in of the first dominant programming model. → Opportunity: tooling & curricula that make massive concurrency intuitive before neuromorphic/quantum scale.

  3. Vertical Integration Lessons – 3-D IC, fiber logic, and open OS timelines emphasize the power of controlling adjacent layers (hardware, OS, compiler). → Opportunity: solopreneur platforms can bundle AI models + vertical dev-kits for domain experts (e.g., photonics, biotech).

  4. Missed AI-Centric OS – LISP-machine world hints at what an AI-native operating system could offer (automatic reasoning, semantic FS). → Opportunity: build LLM-first personal computing layers that treat knowledge graphs as filesystems.

  5. Alternate Energy Constraints – ECL and 3-D heat crises foreshadow today’s data-center power pinch. → Opportunity: invest in cooling tech (microfluidic, immersion) and low-energy accelerators for edge devices.

Next steps if you’d like to dig deeper

  1. Pick a branch → map its component technologies (e.g., optical gates) with TRIZ or Morphological Analysis to uncover modern pivot points.

  2. Scenario simulation → use a system-dynamics tool (Stella, Wolfram System Modeler) to quantify market, energy, and R&D impacts over time.

  3. Innovation workshop → apply your multi-AI-agent framework: one agent collects patents in the alternate tech, another explores modern complements, a third drafts go-to-market experiments.

Let me know which timeline—or which opportunity—interests you most, and we can flesh out concrete prototypes or business models.

Each hike should provide an unique adventure, and be lesser know. Return Format: For each hike, return the name of the hike as I'd find it on AllTrails, then provide the starting address of the hike, the ending address of the hike, distance, drive time, hike duration, and what makes it a cool and unique adventure. Warnings: Be careful to make sure the name of the trail is correct, that it actually exists, and that the time is correct! Context Dump: For context: my girlfriend and I hike a ton! We've don pretty much all of the local SF hikes, whether that's Presidio or Golden Gate Park. we definitely want to get out of town -- we did mount tam pretty recently, the whole thing from the beginning of the stairs to Stinson -- it was really long and we are def...

#3105 Federal and State Spending Idiocy A historic highway overpass for animals cost nearly $100 million and is almost done https://www.yahoo.com/news/historic-highway-overpass-animals-cost-100115264.html #3105 Considering that a state is building a 100-foot wide grass covered overpass across 6 lanes of interstate and shoulders, describe all budget items and the total budget for this task. Reasoned about overpass construction budgeting for a few seconds I'm mapping out a budget for a 100-foot wide grass-covered overpass. Categories include design, permitting, site preparation, structural construction, landscaping, signage, safety features, environmental mitigation, traffic management, and contingency, totaling an approximate $20-30 million. Below is a sample, high-level breakdown of typical budget items for constructing a 100-foot-wide, grass-covered overpass across six interstate lanes (plus shoulders). Actual costs vary significantly depending on location, terrain, materials, lab...
