Below that pictured deck, I have a downstairs deck with redwood posts (done later). Those are also attached the same way but they sagged after a few years. The cable tension is strong and the wood is weaker and "gives" over time. The metal posts are much better for the job IMO. I would not do a cable job on wood posts again - you can use more hardware to terminate the cables and balance the load a bit (imagine a post being pulled from both sides?) but that stuff is pricey as hell, so you try to use only 2 posts for tensioning (one at each end) - that'll fail on wood eventually unless it's bolted like a bank safe. Not saying it's impossible, saying in my experience steel won that one and requires less hardware.
Also it's been 5y and the cables look perfect still, I never maintained them in any way. I like the view they provide, modern, boat like, way more open views as they disappear into the trees or whatever...

Yep, agree with you on the post taking all the tension abuse and eventually it get loose. Problem is, people like wood and so do designers. We brace the end post like if it has to survive the next nuclear bomb so there's no movement.
