Have I gotten complacent?

I’ve not made any changes to my system since 2015 and I mentioned to someone that I’m done, my system is great, and no point in changing anything. Oh sure, if something needs repair, that’s a different story and my very old Linn Arkiv B cartridge can’t last forever. But when I said I was done, the person said I have become complacent (which may not be a bad thing). Does anyone think I’m seriously missing the boat? Take a look at my profile for my gear. Tell it to me straight- good, bad or ugly is all ok. 

Thanks and and let me get back to listening (The Nightfly at the moment; before that some Kenny Burrell)
