Four Tech Developments Worth Watching
This article covers four significant developments from the tech industry: Rivian's micromobility spinoff, Sesame's conversational AI raise, an AWS outage that exposed infrastructure dependencies, and the emerging AI browser competition.
Rivian Spinoff "ALSO": New Micromobility Category
Rivian—known for electric trucks and vans—has spun off its micromobility development work into an independent company called "ALSO." The company has launched a $4,500 electric bike designed primarily for urban delivery work.
The product doesn't fit neatly into existing categories. It resembles a cross between a cargo bike and a small electric scooter, with a large rear cargo platform designed for last-mile delivery. Amazon is among the early commercial customers.
Rivian's strategic rationale: Reapply their accumulated expertise in motor controllers, inverters, and electric drivetrains to a different form factor—opening access to smaller-scale urban mobility markets where large vehicles face practical limitations.
The challenge: The product occupies an ambiguous regulatory category. It's unclear whether it qualifies as a bicycle or a vehicle under existing traffic laws, and urban infrastructure (bike lanes, loading zones) wasn't designed for cargo vehicles of this size. European cities have more established frameworks for cargo e-bikes; American cities will need to catch up.
Rivian sees ALSO as part of a diversified product strategy—reducing dependence on any single large vehicle market while leveraging the same core technology across multiple form factors.

Sesame: $250 Million for Human-Like Conversational AI
Sesame, a conversational AI startup, has raised $250 million with a focus that sets it apart from most AI chatbot companies: voice as the primary interface.
The company's two voice characters—"Maya" and "Miles"—are described by early users as uncannily natural in their pacing, intonation, and emotional responsiveness. The goal is to make talking to an AI feel genuinely different from talking to a machine.
The founding team includes veterans from Oculus and other VR companies, suggesting a longer-term vision that connects to AR/VR interfaces where voice interaction becomes more central than screen tapping.
The open question: Whether voice truly becomes a preferred primary interface. Existing voice assistants (Alexa, Siri, Google Assistant) have achieved significant household penetration but haven't displaced keyboard and touch as the dominant input modes. The gap between "impressive demo" and "people's main way of interacting with technology" remains wide.
Current limitations: LLMs still struggle with executing complex instructions reliably. Voice AI that can hold a natural conversation is impressive; voice AI that can dependably complete multi-step tasks is still developing. The practical value proposition depends on which side of that gap Sesame's system lands on.
Security considerations also apply: voice interfaces introduce risks around prompt injection (unwanted external audio commands) and data retention questions that text-based systems handle differently.
The AWS Outage: A Warning About Internet Concentration
An AWS outage in October 2025 disrupted services ranging from Wordle to Slack, affecting businesses and individuals across a wide range of use cases—including seemingly trivial services like smart home temperature control.
The incident highlighted a structural characteristic of the modern internet: a large share of online services depend on a small number of cloud infrastructure providers. When one of those providers experiences a failure, the effects cascade across industries and use cases that appear unrelated.
The key question: The outage wasn't just about availability—it produced DNS errors and connection failures that made small, simple websites inaccessible. The failure mode exposed how dependent even minimal web infrastructure has become on centralized services.
Christopher Alexander's observation about Bitcoin mining applies here too: systems that optimize heavily for efficiency often build in fragility as a byproduct. Redundancy costs money; companies systematically underinvest in it until a failure makes the trade-off visible.
For organizations: The AWS outage is a reminder to audit single points of failure in critical infrastructure dependencies and to maintain realistic recovery plans for scenarios where primary cloud services become unavailable.
The AI Browser War: OpenAI and Others Target Chrome's Position
The browser market is entering a new competitive phase. OpenAI is developing a browser with ChatGPT as its core engine ("ChatGPT Atlas"), and competing AI-native browsers have also emerged.
These AI browsers differ from conventional browsers in a fundamental way: they don't just display web pages—they include agent functionality that can actively navigate, search, and interact with web content on behalf of the user.
The appeal: A browser that understands intent rather than just executing commands. Instead of "go to website X, search for Y, click Z," the user states a goal and the browser figures out the steps.
The concerns:
- If AI decides which information to display first, it introduces filtering that can serve undisclosed commercial interests
- The open web's value has always included user agency—the ability to browse freely without algorithmic intermediaries deciding what's relevant
- Trust built over decades by Google, Safari, and Firefox doesn't transfer automatically to new entrants, especially ones that change fundamental browsing behavior
The tension between "AI that's genuinely helpful" and "AI that optimizes for engagement or revenue" will be central to how AI browsers are evaluated over the next few years.
Summary
These four developments share a common theme: transformative potential paired with unresolved risk.
- Rivian/ALSO: Promising technology, unresolved regulatory and infrastructure questions
- Sesame: Impressive capability, uncertain whether voice becomes the primary interface
- AWS outage: Real fragility in critical infrastructure, slow organizational responses to known risks
- AI browsers: Genuine utility improvement, meaningful questions about information control
In each case, the technology itself isn't the limiting factor—it's the surrounding systems (regulation, infrastructure, trust, governance) that will determine how quickly the potential is realized and at what cost.
