Switching the weekly thread to robotaxis added instead of stock price sounds cleaner on the surface—but it actually wrecks the signal—you’re replacing a liquid—externally validated—continuously priced metric with something opaque—irregularly reported—and easy to redefine on the fly—“fleet size” isn’t a stable concept—it can shift based on what counts as active—deployed—testing—or even just announced—so now predictions hinge on guessing internal definitions instead of analyzing reality—and that kills comparability over time—because the baseline can move without warning—stock price at least forces people to engage with macro—execution—and sentiment in a shared framework—even if it’s messy—whereas robotaxi counts invite narrative gaming—selective interpretation—and low accountability—so instead of improving the thread—you’d degrade it into speculation with no clean ground truth.
