So then you are looking at specialized equipment thinking it can replace a human at a generic job? I think you are doing a couple of things wring here: underestimating our desire to build generic robots while overestimating capacity of specialized equipment to replace people at generic jobs within newer companies that don't have the capital to acquire or build very specialized equipment. In either case I think my points still stand, if the equipment is too specialized and expensive, humans can compete if they can provide quality, if the equipment is so general purpose and ubiquitous that anybody can afford it with a few months of pay, then people would be acquiring it to rent it out to businesses or to do jobs just like the owner operator truck drivers of today.
