but what do you consider to be the primary threat to an early keyboard failure? Dust and heat cannot be equally threatening. Unless of course you eat on the thing or have it exposed to very high temperatures...Just bad design. Same as Note 7, they wanted too much.
Too small key travel means dust will be a far larger issue than for other keyboards. Tight key margins mean less space for dust to get it, but also means that tolerances are not sufficient for all thermal scenarios (0 degrees in winter in a backpack, 60 degrees under heavy load).
Same as for battery margins (see the Note 7 fiasco), keyboards have a point, where aesthetics starts to interfere with with function. 2016 Macbooks went over that tipping point in my opinion. The only possible solution I see are touchscreens with more precise haptic feedback (4, 5+) miniature servos, which work simultaneously and with different strengths when keys are pressed (so you know which part of the keyboard was pressed).
Or... you know... just making the damn thing 2mm thicker.
Probably at the root of the issue is the small travel distance means the rebound force isn't great enough to overcome a relatively small chance in friction caused by dust or the distortions caused by heat.
So would you recommend using a keyboard cover? Many claim that it makes things worse, as it prevents heat dissipation. Would love to hear your views...I like your explanation so far.
I just want to add that all that empty space below the keys in the previous generations of the Macbooks were really a margin or a buffer zone. Plenty of hair and dust gets under the key caps but the margin of space makes sure that they are not impinging on or pinching into the scissor assembly, which was also less delicate than the current models.

There's probably no way to be 100% sure of it. However, based on my experience (very good care of the laptop and regular cleaning but a workload involving frequent, sustained high CPU usage), I'll wager my 2 cents on heat.
EDIT: the fact that users consistently report certain specific keys to be more prone to failure (e.g. the "b", the "n" or the space bar) might be another argument in favor of the heat hypothesis. It's unlikely, I think, that dust/debris would selectively affect some particular keys, while in the case of heat it would make more sense as it could be related to the hardware components located under each section of the keyboard.
If the macbook has the same keyboard and no fan, then it must be the heat from the MBP. How can it be the dust? thoughts?I don't think its one thing, but rather a combination of small issues that contribute to a larger overall failure. I think this is why many people have reported not having any issues, while others have gone through 3 or more keyboards. The root of the issue, imo, is that the design is failing, but (Correct me if i'm wrong), the MacBook has a similar keyboard and has not had anywhere near this level of keyboard problems, so its not the design alone
the MB still generates heat, indeed it can actually be worse as there's no active cooling to disperse it.If the macbook has the same keyboard and no fan, then it must be the heat from the MBP. How can it be the dust? thoughts?
What a mystery, huh?the MB still generates heat, indeed it can actually be worse as there's no active cooling to disperse it.
I suppose as an additional consideration, the MB is less likely to be used intensively enough to get very hot, and probably not for as long a period or over as many consecutive days as a MBP will, so it could still be a factor... but overall I think it's just a case that the tolerances the keyboard operates to are too fine for real world usage, how Apple responds to that is yet to be seenWhat a mystery, huh?
Actually the inverse, in that MBP is better at evacuating the heat, given the fans.If the macbook has the same keyboard and no fan, then it must be the heat from the MBP. How can it be the dust? thoughts?
but more heat... and obviously not enough fans maybe?Actually the inverse, in that MBP is better at evacuating the heat, given the fans.
Does it? I've not seen anything that would indicate that the current models run hotter then usual. What's your average temperature on your MBP?but more heat... and obviously not enough fans maybe?
I'm just saying... most probably macbook pros run hotter than macbooks...Does it? I've not seen anything that would indicate that the current models run hotter then usual. What's your average temperature on your MBP?

since the keyboards are the same, that's the only difference left (other than the probable longer exposure / use of the pros)
So, the only conclusion is that the cooling system must not be sufficient/efficient or fast enough?
