The speaker predicts a future scenario where Optimus humanoid robots become sufficiently capable to be sold commercially. A key aspect of this model is the monthly software fee, which is expected to be "thousands of dollars." This high cost is justified by the robots' ability to perform tasks typically done by humans earning "$100,000 or more a year." The economic efficiency of these robots is so significant that, within approximately one year, a single Optimus robot will generate enough value to cover the cost of building another.
