“DoorDash problem” defined: AI agents sit between users and service providers, stripping away monetizable layers like ads, reviews, loyalty, and upsells, reducing platforms to commodity backends.
Threat to App-era companies: Uber, Lyft, Airbnb, DoorDash, TaskRabbit, ZocDoc risk losing direct customer relationships that fund their business models.
AI agents don’t care about monetization: They choose cheapest/fastest options, bypassing differentiation, brand, and promotional economics.
Service-provider dilemma: Continue supporting agentic access and risk commoditization, or block agents and risk losing customers.
Amazon vs Perplexity lawsuit: First major clash; Amazon argues Perplexity violated ToS, masked bots as humans, and circumvented blocks.
High stakes for Amazon:
- Massive ad business ($60B+) threatened by agentic shopping that hides ads.
- Prime’s stickiness weakened if AI agents shop anywhere automatically.
Amazon retail already commoditized; easy for agents

🧰 What You’ll Need

Raspberry Pi 5 running Raspberry Pi OS
Little Bird Toucan HAT (8 × APA102 LEDs)
Python 3
The spidev and time modules (standard or installable via apt/pip)

⚙️ Wiring / Setup

The linux/arm and linux/arm64 targets will cover most Raspberry Pi models, but you need to set GOARM properly when targeting 32-bit ARM devices.

Mapping Raspberry Pi Models to Go Architectures

Raspberry Pi Model	Go Architecture
Raspberry Pi 1 (A, B, A+, B+), Zero, Zero W	`GOARCH=arm GOARM=6`
Raspberry Pi 2 (v1.1)	`GOARCH=arm GOARM=7`
Raspberry Pi 2 (v1.2), 3, 3+, CM3	`GOARCH=arm GOARM=7`
Raspberry Pi 4, 400, CM4 (32-bit OS)	`GOARCH=arm GOARM=7`
Raspberry Pi 4, 400, CM4 (64-bit OS)	`GOARCH=arm64`
