Seems like a very political answer from Andrej. Of course he’s not going to outright say “yeah, we’re prioritizing the profit margin over accuracy and safety considerations” if he wants to keep his job, but that seems to be the short of it. Others may choose to follow, at least in the short term, but it won’t be because of “entropy” making the system worse (you can always build a model without a data source and then refine the results based on the added value of a data source) but doing so just because it will save lives doesn’t cut it when the goal is to cut corners and costs to maximize profit. I can believe that some types of sensors aren’t worth the trouble in terms of additional signal to noise ratio, but I can’t believe this is one of them.
The entropty he's taking about comes from many sources, in particular opening yourself up to maintenance or supply side errors, and just overloading team attention (always at a premium) for no net return. It's not just CPU cycles (although that's part of it, that hardware could be doing something else useful.)
