Imagine if a movie were shown only once. Or your local newspaper was read out just once a day in the local square. Or novelists read their books out once to an invited audience. That's face-to-face lectures for you: it's that stupid.Jeebus, those are some terrible analogies right there. Even if we bypass the fact that movies and novels don't fulfil the same roles as newspapers - let's just consider the strict subsets of documentaries and novels with some genuine thesis underlying them - if a novelist divided their reading into twice-weekly chunks which came attached to group discussion and small Q&A sessions, there's a hell of a lot one could learn from that approach. The problem isn't the effectiveness of the lecture as a tool, it's whether the surrounding context supports that tool, and whether the lectures themselves are of the necessary quality. For instance:
What's even worse is that, at many conferences I attend, someone reads out an entire lecture verbatim from their notes. Is there anything more pointless? It's a throwback to a non-literate age. I can read. In fact, I can read faster than they can speak. The whole thing is an insult to the audience.That's where the problem is. Not that lectures are used, but because there's a distressing number of academics who don't bother to distinguish between reciting notes and teaching students.
The same problem surfaces when we get into Clark's 10 reasons for why lectures allegedly suck. Points 5 to 9 are probably reasonable criticisms of lectures in general, though 6 ignores the fact that other sessions exist in university courses to combat that problem (see above), and 8 and 9 are at worst double-edged swords - the benefits to peer communication of putting people in the same room at the same time to experience the same lecture should be entirely fucking obvious. Points 2, 3 and 10 are entirely aimed at poor lecturing technique, with 2 and 10 in particular not even remotely being solved by switching to pre-recorded lectures (in fact, those problems might be exacerbated), and point 4 is similarly unsolvable by the proposed switch to MOOCs and the like. Point 1 is just point 3 reworded so as to look smarter by mentioning the Babylonians.
Out of the 10 points, it's really only 5 and 7 that definitely hit home as reasons why lectures are fundamentally flawed, as oppose to far too often delivered by gitlizards. The ability to take in lectures at one's own pace is incredibly important, and by insisting otherwise lecturers are guilty of ableism. I'm perfectly happy with the idea that lectures should be recorded. Indeed, plenty of students do so here at my current place of employment, though I'm entirely receptive to an argument that we should be doing it ourselves with visual as well as audio (generally the students only record my voice) and sticking it up online after the event. But whilst as educators (as well as minimally decent human beings) we should make every effort to ensure those who can't get the most from a live lecture as we'd like are in no way disadvantaged by that, the general benefits of delivering material to groups of people who can interact with each other and you immediately afterwards (I can't remember the last time I gave a lecture which didn't then lead to some short but useful conversations with students just after finishing up) are real and shouldn't be wished away, in the same way that realising some people require Braille isn't a sensible argument for giving up on printing presses.
Every approach has its advantages and its limitations. Supplementation and variation are the approaches we need to focus on. And if too many academics can't even deliver a half-decent lecture (and I am as disgusted as anyone by the fact that so many can't) we need to teach them to do it better lectures, or kick them to the curb. Because these goobers can't manage a lecture, how can we trust them to deliver anything more involved ? We can't make teaching better without making better teachers, even if we try to rely on the online causes that Clark just so happens to make his shekels slapping together.
 I'd also like to point out the irony in Clark trying to sell academics on the idea that MOOCs would reduce the amount of time they spend teaching instead of researching, when it's exactly that attitude of seeing teaching as an impediment to research that leads to shitty lecturers in the first place.
