Yeah I'm really on the fence about this. I mean, obviously robots that do basic floor cleaning and stuff all right. Done deal but a general purpose robot that can clean intricate surfaces. Disinfect things, put tools into sterilization etc etc. I don't know if that is right around the corner or not. Aside from floors, do you think that we will have robots doing all the rest of janitors work in the next half decade? Anyway, That's why I said janitors in hospitals and in specific I don't think janitors in offices For example, going to have their jobs very much longer
