Adrian Wong, the Google Glass engineer who defected to Facebook, quietly rejoined Google

Context & Ripple Effects
Wong's quiet return closes a small loop in the mid-2010s Google–Facebook talent war: he was part of the Glass engineering bench that Facebook raided, in the same period Facebook poached ATAP chief Regina Dugan, an exodus that reshaped what remained of Google's moonshot group into something more focused on shipping product, as covered in the earlier look at how ATAP changed after Facebook hired its chief.
The move also lands during visible churn on the other side: Facebook had just parted ways with engineering VP Cory Ondrejka months after the Oculus acquisition, per the report on Ondrejka's departure, making Wong's exit one more data point in the two companies' revolving door.
First-order effects
- Google gets back a proven consumer-hardware engineer from the Glass program without paying a recruiting premium, while Facebook loses embedded knowledge of how Google ran its most scrutinized hardware bet.
- For Wong personally, the return reverses the defection that made him a named player in the Google-to-Facebook pipeline Business Insider tracked.
Second-order effects
- Facebook, already bleeding senior engineering leadership after the Ondrejka exit, faces a harder sell when pitching ex-Googlers on staying — retention pressure falls disproportionately on the side losing people.
- Each high-profile boomerang lowers the stigma of going back, which historically pulls more defectors with it — Gabriel Stricker's own return from Twitter to lead Fiber communications weeks later fits the same pattern, as does the much later wave of returns to Google like Jacob Devlin leaving OpenAI and coming back, and the Laserlike founders rejoining from Apple.
Third-order effects
- If boomeranging keeps normalizing, big-company talent strategy shifts from 'poach or be poached' to managing alumni as a reusable pool — rivals become talent lenders rather than permanent losses, and compensation fights center on equity cliffs and counteroffers rather than first hires.
- It also suggests the Glass-era brain drain was cyclical rather than structural: moonshot groups lose people when their missions drift toward shipping, and regain them when those missions stabilize.
The trend: Silicon Valley's flagship labs are settling into a permanent revolving door, where star engineers cycle between Google, Facebook, Apple, and OpenAI rather than defecting once.
