I'm not claiming it will be linear or will not be linear. I'm saying it's a bad idea to assume either when trying to predict the future.

  The problem is: you have to assume "something", because otherwise you simply can't make any predictions. Either assume progress is linear (which seems to be the instinctive default most people use if they don't know much about a particular field) or assume it's non-linear. In case of the latter, you can choose between assuming exponential progress to apply or a step-wise, non-continuous kind of progress. It's a bad idea to not assume one of these to be the case if you want to make a prediction, because it's not possible to predict anything without that assumption. I mean, you can of course refrain from making any predictions. But I have never met a single person who could resist the instinctive urge to extrapolate current developments into the future. It is as much a core part of being human to do this as it is to breathe air.

    It's the assumption of linearity in combination with anecdotes that make the prediction weak, not the assumption itself. If you hold that assumption and use a variety of data to justify it and extrapolate from that's different than what I was criticizing.
