This just seems completely wrong. The wrongness comes from conflating completely orthogonal concepts: speed of detection, speed of response and "smartness". The fly is very fast at detecting and responding to motion in its vicinity, but that property does not make the author look foolish, just slow.
It seems like a strange mistake to make, given the article's musings on different time scales of thought in e.g. plants. If the author applied the same analysis as they do in the quote above, then obviously us humans make the trees look foolish because we can detect and react to things so quickly. I don't think they believe that about a human/tree comparison, so I have no idea why they would close an article with the same comparison and conclusion between a human and a fly.
Actually the author is using the wrong technique if he is trying to swat the fly.
Flies use their compound eyes and a collection of sensitive hairs on their bodies to detect threats and avoid being swatted. You can use this to your advantage.
When the fly lands on something you should approach slowly and steadily from the same direction with your palms open and ready to clap together. Move slowly as your hands get close to the fly so as to cause a minimal air disturbance. By moving slowly, the fly finds it difficult to parse the fact that your hands are getting closer and once you are within a foot or so (.3m) clap your hands together as fast as possible.
Your hands will be close enough that even with the fly's excellent acceleration and detection skills it will be difficult for the fly to escape being crushed. Make sure your fingers are cupped so that the fly is spit out between them as the air escapes during the clap.
It may help to consider that many times a fly will launch itself slightly backwards when it takes flight before zipping forward rapidly. Plan your clap so that the fly will be trapped even if they shift backwards slightly.
Wash your hands when you're done.
This method is successful for me more than 95% of the time when I allow the fly to land. If the fly is nervously zipping around just be patient. It will pause and then you can clap.
You also avoid the mess left behind when clapping them. And in some way it also feels better.
It's actually a fun hobby of mine and after a while you can catch them nearly always. I also love watching my children trying to copy my approach. Highly recommended!
You should keep trying buddy. Try approaching your hand to a fly very slowly and when the distance will be ~20cm slap it with one powerful movement. Remember that a fly survives ~70% of slaps because it manages to hide between your fingers or something - you need to kill it after slap with squeezing. Keep trying and you will be able to kill flies with your hand with 50% efficiency in average. There are even easier way of killing a fly btw, for example do slowly approaching it with a thin pin which is too hard for a fly to see it coming.
Use a spray bottle to get its wings wet, I usually use Windex or a multi-surface cleaner, then get a paper towel and kill it as slow or as fast as you want
A tree can afford any amount of thinking-stuff, because running it slowly can be an arbitrarily tiny part of its energy budget: trees can afford to be very, very smart. What remains is to find how intelligence could enable reproductively advantageous adaptive behavior in trees. What could a smarter tree do to outcompete rivals?
It would be foolish to assume there are no such opportunities.
> trees can afford to be very, very smart.
Hopefully I can use some of my perspective to address your follow-on question:
> What could a smarter tree do to outcompete rivals?
This may represent a limited understanding of Darwinian evolution.
Trees have an economy, sharing resources with each other and with other living things.
Tree also are (more or less) fixed in place, thus these economic games are repeated games with known participants.
They thus have a vested interest in maximizing the wealth of the community, rather than their individual wealth. They may (and studies suggest they do) have a preference for supporting their offspring over other trees, but not to the point of killing the community their offspring will also depend on.
Where I am going with this. Repeated economic games are not zero-sum; the pie can get bigger. "Competition" in this setting does not look like competition in a zero-sum "I have to beat the other guy" game.
What trees can do with their intelligence is learn how to build long-term stable and nuturing communities which generate substantial wealth for many members. And that this is a logical local (perhaps global) optimium.
Mutualism is a well-proven successful strategy. There does seem more scope for intelligence in crafting positive-sum arrangements than in simply competing. (Arguably our own brains hypertrophied in response to sexual selection of better storytellers, with other results secondary.)
Nature did, in fact, explore the winged-bipeds body plan to full fruition twice, once in mammals, and did winged quadrupeds before and again in mammals. She is progressing on a another as I write this. And, humans did end up conquering the air without growing wings. Nature isn't picky about methods.
I know, definitely not, but it's a thought I amuse myself with.
If we assume trees are smarter than us, and speeding it up 1000 times brought them down to our level...
and conversely, if we could learn to think slower, would we be smarter?
Only when you slow down to a thought speed of a tree, you can fully enjoy the beauty of this world.
It made me think about timescales very much: if trees moved at human scale time, we'd think about them in a totally different way, and I'm sure would be very much more open to the notion that they're intelligent in many ways.

I'm not convinced that the visual/time part of this is correct. If we follow the analogy with sonic fusion frequency ... there's a point at which a repeating sound will change from being a rythmic experience and instead becomes a pitch. So, if you are in an acoustic environment that is generally filled with pitch information, and you could somehow shift your sonic fusion frequency ... if you moved it down, even some of the non-pitch sounds will become pitches; if you move it up, some of the pitches (the lower ones) will now be perceived as rhythmns instead. But ... and this is the important part ... the actual frequencies of the sounds will not change at all. So there's a fixed physical phenomenon (acoustic pressure waves at various frequencies) which does not change, but the sonic fusion frequency determines what kind of experience we have when we encounter that phenomenon. Notice though, that it's a more or less binary switch: either we perceive N Hz as a pitch or as a rythmn, and varying the fusion frequency doesn't alter that. Nor does it various the actual physical frequencies of the sounds - they continue to be whatever they were.
I suspect this is likely true for visual fusion frequencies too.
Moreover, the comparison with video and/or film is misleading. In those cases, the actual phenomena are a discrete series of images that because of CFFF end up being perceived (or not) as continuous motion. But when looking at the actual world, to within the limits of our senses, ALL phenomena are continuous. If an insect flies across your field of vision, there are no distinct series of images that your brain does (or does not) fuse into continuous motion. There is only a continuous motion, which you may or may not notice (the whole thing may happen too fast for you to even register the entire pass.
CFFF, if I understand correctly, is measuring how fast you need to present discrete visual information for the brain to "fuse" it into continuous information (such as motion, or a persistently "on" LED light. But this doesn't seem to have anything to do with how we and other animals perceive reality, because reality is not a series of discrete images. I don't believe that CFFF has much to do with our ability to perceive time, or even with limit questions such as "how long must something be in our visual field in order to notice that it was there".
Could be that I'm missing something huge here, in which case I hope that Benn or someone else will correct me.
They shelter quantity of animals, feed billions of more or less microscopic living creatures (insects, mushrooms, bacteria), induce rain, create an environment with ideal climatic conditions, prevent landslides, provide us incredible useful resources (wood, fruits, substances for medication)... Not even talking about the air you're breathing. And when they die, it's another cycle of benefits that begins.
Meanwhile we may have invented iPads, but as for now, we are at the exact opposite of trees and only know to live the destructive way.
Please, don't do drugs. If you play with fire, you might get burned.
There is an alternative. Play with electricity! With a plasma globe. And a radiometer.
What happens when you wave a plasma globe next to high-voltage power cables under a bridge, alone at night? Nothing unusual. What happened when I walked away afterwards? I felt different. Touching a tree made a grounding point.
Yes, ground loops are real. DC and AC are real. Trees are smart, they grow. They're still alive. So are you and I. Let's play in this world and discover something new!
Fire requires caution. Matches aren't for everyone. But we don't ban lighters for adults, nor would it be smart to.
The incredible health and therapeutic potential in mind altering substances has been held back long enough. It's time for facing reality; ironically enough.
The material science is good at dealing with material in general, but it is not the proving method that is illogical but the assumption needs to be challenged altogether
