It seems that AoT's have some flexibility for upgrading/adding sensors. However, I am concerned about a scenario where one would need a "deeper" hardware upgrade of the sensors/Linux SBC box (e.g. need to change the whole Linux motherboard). When it comes to computation, hardware has a tendency to age quite fast, especially if software side becomes more computationally expensive (e.g. more computationally intensive machine learning). Moreover, even without this demand-side induced aging, I would imagine hardware just wears out in general. This may be even more of an issue if there are hundreds of such boxes to maintain. So the question is how hardware-upgradable (i.e. future-proof) are these boxes? Ideally, I would imagine a more modular plug-n-play design is needed if that is not already the case.
