Episode: Meta Smartglasses Leak

Overview

In this episode, Brian McCullough covers a leak revealing Meta’s next generation of smartglasses, an OpenAI breakthrough in AI coding tools, major TikTok developments between the US and China, Spotify’s latest features for free users, and a hands-on guide to iOS 26’s new call screening. The tone remains brisk, informed, and conversational—true to “Silicon Valley’s water cooler podcast.”

Key Discussion Points & Insights

1. Meta’s Smartglasses Leak

[00:04 - 03:43]

• Unlisted Meta Video Leak

  • Meta accidentally posted (then removed) a sneak peek of upcoming Ray-Ban branded smartglasses featuring a heads-up display (HUD) for one eye, aimed at navigation and responses via a specialized SEMG wristband.
  • “To be clear, this is not true AR and it’s far less ambitious than the Orion prototype. The clip shows the fixed HUD visible to the right eye only being used for Meta AI and on foot navigation…” (Brian McCullough, quoting Upload VR, [00:13])

• Partnership and Brand Dynamics

  • Originally, Ray-Ban parent Essilor Luxottica had concerns about the thickness needed for the display and almost walked away from the project.
  • A reported €3B investment by Meta (raising their stake in Essilor Luxottica to over 5%) appears to have revived the collaboration, enabling Ray-Ban luxury branding.
  • “The Ray-Ban branding should lead to much wider consumer appeal than had Meta gone alone…” [01:55]

• Wider Reach and Consumer Strategy

  • Branded appeal could allow the glasses to be sold in thousands of retail locations.
  • Physical details: glasses expected to weigh 70g, up from previous models’ 50g.

• Oakley “Sphaera” Edition Revealed

  • A leak also showcased Oakley-branded “Meta Sphaera” glasses targeting athletes, with a centered camera for first-person video.
  • These won’t have a display but will include a camera, microphone, and speakers for action sports.
  • “A centered camera would be ideal for first person footage and the product will be marketed toward cyclists and other athletes…” ([02:59])

2. OpenAI’s GPT-5 Codex for Coding

[03:52 - 06:14]

• Announcing GPT-5 Codex

  • OpenAI debuts an advanced coding model, GPT-5 Codex, optimized for “agentic coding” (i.e., more autonomous problem-solving).
  • The model dynamically allocates computation time—spanning from seconds to up to seven hours—depending on task complexity.

• Performance Benchmarks

  • Outperforms previous models in agentic coding, code refactoring, and code review tasks.
  • Software engineers found GPT-5 Codex “submitted fewer incorrect review comments” and more “high impact comments” than predecessors.

• Technical Detail

  • “GPT5 codecs works similarly [to ChatGPT’s router] but has no router under the hood and can adjust for how long to work on a task in real time… I’ve seen the model take upwards of seven hours in some cases.” (Alexander Ambrosios, [05:41])

• Market Competition

  • The competitive landscape for AI coding tools is heating up, with Claude Code, Anysphere’s Cursor, and Windsurf also mentioned as rivals.
  • Cursor reached $500M ARR in 2025; Windsurf’s acquisition drama highlighted.

3. TikTok/ByteDance-US Algorithm Licensing Deal

[06:23 - 09:36]

• Breakthrough in TikTok US Spinoff

  • A deal framework emerges: TikTok’s US spinoff will license the Chinese recommendation algorithm and other IP from ByteDance, rather than fully severing ties.
  • “Beijing wants to be seen as exporting Chinese technology to the US and the world.” (Asia-based ByteDance investor, [08:26])
  • U.S. officials still question whether American control over content and data is sufficient.

• Deal Participants & Terms

  • Discussions involve major investors (Andreessen Horowitz, Blackstone, General Atlantic, KKR, Oracle).
  • Oracle to have a small holding and oversee data security.
  • The structure aims for American investors to control the spun-off app, but with Chinese technical DNA retained.
  • Past proposals had new US investors joining as Chinese firms’ stakes dilute.

• Geopolitical Implications

  • “It’s the ultimate taco trade, said one US Advisor close to the deal, referring to the acronym—Trump Always Chickens Out. After all this, China keeps the algorithm…” (US Advisor, [09:19])

4. Spotify’s Free User Upgrades

[10:13 - 13:34]

• Huge Free User Base & New Features

  • 433 million global monthly actives use Spotify’s free, ad-supported tier.
  • New options: “Pick and Play,” “Search and Play,” and “Share and Play”—let users queue up any song, not just shuffle playlists.
  • Social sharing is improved, with Instagram integration highlighted.

• Limitations Still Apply

  • Free users gain “on-demand time” before defaults revert to shuffle/limited skips.
  • “Spotify did not share what that [on-demand] time limit is, but noted that premium users will not have these restrictions.” ([13:02])

5. iOS 26: Liquid Glass Design and Call Screening

[13:34 - 19:18]

• Design Overhaul

  • The new “Liquid Glass” interface brings cohesive, rounded, translucent elements and dynamic lighting across all Apple platforms—iOS, iPadOS, macOS (Tahoe), WatchOS, VisionOS, TVOS.
  • “Interface leans into rounded, translucent surfaces, depth and dynamic lighting… but it doesn’t force you to relearn the phone. Navigation and core behaviors remain familiar...” (CNET, [15:20])

• Notable New Features

  • Call screening in the Phone app: users can have unsaved callers state a reason; transcripts are delivered before your phone rings.
    • “If you tap Ask Reason Calling, your phone will ask anyone who calls you from an unsaved number the reason for their call without ringing your iPhone…” ([17:19])
  • Small but impactful upgrades: call hold assist, haptic reminders, live call translation, and a new system-wide Games app.

• Limitations and Criticisms

  • Some readability issues under certain lighting/wallpaper combos.
  • Advanced new features most visible on newer hardware.
  • The “Agent Y” Siri revamp is absent at launch, making the update feel “visually new but only incrementally smarter from day one.”
  • “My wife has not taken her phone off silent in months and she remains blissfully unbothered by spam calls.” (Brian McCullough, [18:45])

Notable Quotes & Memorable Moments

• “The Ray Ban branding should lead to much wider consumer appeal than had Meta gone alone, as well as the potential to demo and sell the glasses in some of Essilor Luxottica’s thousands of stores worldwide.” (Brian McCullough, quoting, [01:55])
• “Much of the increased performance was thanks to GPT5 Codex’s dynamic thinking abilities… can decide five minutes into a problem it needs to spend another hour.” (Alexander Ambrosios, [05:41])
• “Beijing wants to be seen as exporting Chinese technology to the US and the world.” (Asia-based ByteDance investor, [08:26])
• “It’s the ultimate taco trade, said one US Advisor close to the deal, referring to the acronym—Trump Always Chickens Out. After all this, China keeps the algorithm…” (US Advisor, [09:19])
• “If you tap Ask Reason Calling, your phone will ask anyone who calls you from an unsaved number the reason for their call without ringing your iPhone... Then you can decide whether or not you want to answer the call.” (Brian McCullough, [17:19])
• “Remember you can always silence your phone and not be bothered by any phone calls. My wife has not taken her phone off silent in months and she remains blissfully unbothered by spam calls.” (Brian McCullough, [18:45])
