Shelf life of mirrorless Cameras: life after DSLR.

I bought my Sony A7riv just before covid, i think in 2019, and its got some serious mileage on it despite me no longer doing weddings... Im at 198K

It used to be, you could just let your camera do the talking for you, and youd wait for a shutter to give out, or need something better for low light, and lenses could theoretically be owned for 10+ years before needed upgrades..

This thing still is a workhorse, its in decent shape (i dont baby gear, i work with dogs, they have peanut butter stuck in places, and drool embedded on it, scratches.. ect, same with my lenses. )

But is there a shelf life for the mirrorless? The only tech i could see REALLY needing in the future is maybe the wifi on it dies.. and im sure Eye Tracking has improved significantly, so what are we considering the "max life" of a mirrorless camera?
