The question was whether, when programming the algorithm (until the contract was formed), the programmer was doing so with actual or constructive knowledge of the fact that the relevant offer would only ever be accepted by a party operating under such a mistake (and not to the specific incident per se).
There was no mistake as to a term, but at most a mistaken assumption.
CA preferred an "incremental adjustment" of the law over "fundamental redesign" where the existing rules are adequate. Redesign is preferably done by the legislature (e.g. RecordTV software v. set-top box amendments to CA).
The responsibility for AI decision-making, at least for deterministic systems, are still to be attributed to the programmer, albeit concepts like knowledge had to be adapted.
