Automated machinery and robots have seen low-level tasks in a factory environment be made redundant. With that in mind – and with technology constantly pushing the boundaries of what is possible – it’s a safe bet that soon more complex jobs will also be made redundant with these innovations.If we look at an example put forth by The Boston Consulting Group in 2015, the average welder earnt around $25USD an hour (approximately $37AUD), whereas the equivalent operating costs of a robot to do the same job would’ve been more like $8USD an hour (approximately $12AUD).When shown using numbers, it’s a startling fact that robots and automated machinery have cheaper overall operating costs. They are also immune to human error – which is something that compromises the quality of a product on occasion. Robots and automated machines are also immune to harm, in a manner of speaking.
