From a stalled food-delivery law to a landline fight that may strip the CPUC of its own authority, California's technology regulatory apparatus shares a recurring flaw: the gap between formal rulemaking and real-world accountability keeps widening.

California is not short on tech regulation. It is short on tech regulation that does anything.

Three stories this week, read together, describe the same structural failure at different altitudes. AB 578, a consumer and worker protection law for food-delivery platforms, went into effect January 1 — and six months on there has been no public enforcement action and no documented change in platform behavior. AT&T's filing to decommission copper landlines at 360 California wire centers by June 2027 has drawn formal opposition from the CPUC, Marin County, Berkeley, and San Francisco — yet the more consequential threat to that fight may be internal: Assembly Constitutional Amendment 9 (ACA 9), currently advancing through the legislature, would remove the state constitution's requirement that telecom providers be regulated as public utilities under the CPUC at all, potentially stripping the agency of the authority it is now trying to exercise. And Waymo's July 4th operational failures — drained batteries, towed vehicles, gridlocked streets — unfolded inside a dual-permit system requiring both DMV and CPUC sign-off for fare-charging robotaxis, a structural arrangement that documents oversight without necessarily producing it.

The pattern runs deeper than any single agency. A June 2025 report commissioned by Governor Newsom recommended a "trust but verify" framework for frontier AI, including third-party audits and adaptive thresholds. No state agency has been publicly designated to implement it, per the report itself. For gig workers, labor standards enforcement falls to the Division of Labor Standards Enforcement while the CPUC handles adjacent infrastructure questions — a split that leaves both functions weakly executed. California's regulatory architecture is not a wall; it is a series of adjacent fences, each agency pointing at the next when something gets through.

This is the context in which the AT&T landline fight should be read. The CPUC is fighting — correctly — to preserve Carrier of Last Resort protections for roughly 199,000 customers. But the agency is doing so under a constitutional framework that ACA 9 would dismantle, and alongside a federal preemption claim from AT&T that treats state telecom authority as an obstacle rather than a check. Sacramento can write the rule and lose the jurisdiction simultaneously.

What to watch: ACA 9's progress through the legislature; whether the CPUC's formal opposition to AT&T's FCC filing survives a preemption ruling; and whether the DLSE logs any AB 578 enforcement action before the law's first anniversary in January 2027. Silence on any of those fronts will say more than the statutes do.
