Let's look at where my DSLR struggles begin. My Nikon D800 from 2012 is an extra 50% heavier than the Nikon Z6 II I'm now used to, and also the Z7 II that is arguably my DSLR's modern day equivalent.
I first used the Nikon D610 when it was launched back in 2013. A lot has happened since then, so surely it's obsolete now?
