To me, the better question is when it will be hackable. To be more specific, before or after end of life.
i'd say somewhere around the year... shit can't find my crystal ball anywhere... ah i'd say 2666, they finally find a software leak, and my great great great never gona happen (i'm sadly never gonna have children) great grand child will finally experience the full joy of pirating games on my patched switch.
i think the best hackers of today are working on a solution.
exploits don't pop out easy.
sometimes it's in exploit.db that there's info found on software installed on a device which is good enough to start from.
mostly it's harder then that, they'll have to reverse all connections in use to find how it works, install multiple hw mods to derive some checks, and these steps might work eventually for the hacker, but are far to complicated to ever sell or put as a DIY...
and making the only one exploit known while patches are still in production is always a high risk, it might get patched, which means the hacker has to start all over from point 0.
team SX did such a thing, see where they're now?
