You also have to consider the dials are the primary flight instrumentation (ha!). This raises issues about accuracy and vehicle inspections, not to mention the odometer. When your oil pressure of temp doesn’t read properly because of a ‘bug’ that’s gonna be a big problem.
Do you trust your digital warning lights? How are you going to simulate the dim glow of the ignition light from a weak alternator? Simulate that flickery oil level gauge or smooth it out? How do you reset the mileometer or change the clock time. Buttons or touchscreen?
It’s not impossible but it is more work than you’d expect.

That sounds like a canard...I'm not sure if you did that intentionally. Are you really going to argue that the old 911 oil level gauge -- the one gauge that was always (even when new) absolutely never to be relied on under any circumstances according to every expert including Wayne Dempsey who we all have to thank for the existence of this very forum as well as numerous books on 911s-- is an accurate gauge that you really can't do without so therefore you can't stomach digitizing your oil level reading.
What is a "digital warning light?" Do you mean a warning light that is triggered by computer code? I'd trust that, if I had one. I have no such warning lights in my car, and either do you if you are talking about a pre-computer 911.

We are not making public policy decisions here. This is a technical discussion about our individual Porsches. And the odometer? That would be pretty stupid to rely on an analog odometer, especially in an old 911. I think you are stuck in the The Office weekly staff meeting with the boss mode, "I'm just saying it raises questions." "It's a slippery slope! It's a slippery slope!" Those check collecting clock watchers in meetings are funny.
It's 2019 and NO ONE, NO ONE makes the argument that digital is less accurate and reliable than analog. The truth is exactly the opposite of what you're saying. Please redeem yourself.
