No robot could do my job.
No robot can do my job as well as I can.
This robot can do my job as well as I can, but i need to catch all the exceptions that it's not smart enough to deal with.
This robot can do my job as well as I can but it needs me around to fix it when it breaks.
This robot can do my job as well as I can.
Why would anyone want to do that job? It's a robot job.
