Firstly we have about two decades where VR will be available but AI will not have been rolled out to every niche it can eventually serve. These things take time and there is plenty of market availble for both technologies. Secondly, absent true general human level AI, it will never make economic sense to automate to 100%. Some percentage of activity is not just rare, but actually unpredictable and that's where you employ humans. Unpredictable stuff happening in toxic industrial environments is not a fun job to do in person though.
