I think it comes down to opportunity cost. In our recent paper (Zhang et al., PNAS, cond. accepted), data from a few months ago suggest some people are already doing this (caveat: some may be non-compliant humans, and things move fast).

I just had Opus 5.5 one shot a Human-Like mousetracking driver by looking at my code on cognition. Right now it's choosing left or right randomly. It's still not perfect but this took it literally a simple prompt and 1.5 mins to code a script. It can then be randomized and used across bot accounts.

ACTION ALERT 🚨 Right now, the Senate is considering adding language to the transportation reauthorization bill to restrict bike lanes. Tell Congress: funding for bike safety projects MUST continue! Take action: action.bikeleague.org/page/101946/...
Action alert graphic. A man holds a sign next to a bike lane that says "Everyone deserves safe streets!" Below the image is white text on a black background: "Tell congress: Funding for Bike Safety Projects MUST Continue! bikeleague.org/action-center"Action alert graphic. White text on a black background: "Congress Must Save America's Bike Lanes
Secretary of Transportation Sean Duffy erased the data that shows bike lanes reduce crashes and don’t cause congestion. Then he asked Congress to defund all bike lanes — and even remove bike lanes from busy roads.

Now, Congress may be listening: the Senate is considering adding language to the transportation reauthorization bill that would restrict what kinds of roads could have bike lanes on them at all. 

We need everyone in Congress to hear us clearly: bike lanes save lives and bicyclists have a right to ride on the roads and get home safely.

Examples of desired research topics include, but are not limited to, computational approaches in human and/or non-human animal models to study perceptual function and sensory loss, learning, motivation, emotion, and/or higher cognition. While we expect the primary appointment to be in our CAB area, there is  potential for cross-affiliation with other departmental areas.The appointment will be 100%-time over the nine-month academic year (late-August to late-May) and will be made at the rank of tenure-track assistant professor, depending on qualifications and experience and consistent with collegiate and University policy. Salary and start-up packages are competitive. The successful applicant should have and is expected to maintain a strong research program, advise graduate students from a variety of different backgrounds, and teach undergraduate and graduate courses, including core courses within the graduate training program. A strong record of teaching and mentorship is desired. The individual will also be expected to contribute to the service needs of the department, college, university, and profession.A successful candidate's application will demonstrate scholarly distinction, a record of publications, teaching commitment and, if applicable to the research program and the candidate’s career stage, evidence of success in securing and/or pursuing extramural funding.Applicants are invited to review the Workload Principles and Guidelines for Regular Faculty in the College of Liberal Arts, as well as the Standards for Promotion and Tenure in the Department of Psychology.
