"by say becoming more lazy i mean instead of changing the res we'll go skiing for a week when to get a good harvest you need to be there every other day at least"

This is not true for larger DWC systems and NFT systems with proper buffers. I've done an SoG setup where I'd only change the buckets every two weeks. Left me plenty of time to go out of state and do what I do best - build custom light systems for massive horticultural firms.
