It's just a gut feeling but I'd trust a feedback based backlash elimination mechanism more than rope based, especially in the long run and/or with a large deployed base.
But, why?
Anyway good engineering requires extensive testing over many hours of movements.
What a horrible video is this, with the robotic translated AI voiceover? Update: Ah, weird, if I watch the non-embedded one on youtube it is the original in English with normal sound. It's the one embedded on his web site which has AI translation to German.
That's not the video's fault, but YouTube's. YouTube has started adding automatic AI voiceover translations to all videos, unless the uploader explicitly disables them for each single video. It's opt-out and the option is well-hidden, so most uploaders will not disable it. As an end user, there's nothing you can do to prevent from seeing them. But you can change the audio track to the original while the video is play…
WHAT?!? It a time when there is a growing animus towards AI generated content, for many content creators this would be tantamount to slander

Like I said gut feeling. I suppose over time there may be some play in the axles, for example. Something feedback could compensate for but a rope could not. Anyway good engineering requires extensive testing over many hours of movements.
He actually discussed this in an earlier video for his initial tests on the capstan drive. He ended up testing the rope he used for around 358 hours (two weeks) on continuous use in the drive itself with very low backlash
Why spend so much effort to achieve an "exact" gear ratio? Having more zeros does not equal to being more "precise". Also, I wonder how resistant this mechanism is to wear and fatigue.

Cara is the Irish word for 'friend'. Not sure if thats what was intended or is just a coincidence.

That would be a terrible path for someone with this extreme level of demonstrated talent, motivation, and follow-through. Much better for someone to fund a startup run by him.
Why would you put someone with clear talent at building stuff in charge of running a startup? He'll get bogged down in lawyers, day to day operations and growth strategies. Hire him and put him in R&D in some robotics company.
Amazing presentation! - somebody hire this kid asap https://www.aaedmusa.com/
I've watched and re-watched Aaed's videos on the capstan drive, it's great stuff. High speed, high torque, compliance, effectively no backlash. It's fascinating to watch a legit engineering mind at work.
I haven't watched the one about the dog, but the one with the initial explication of capstan drives [0] was excellent. I've been dreaming about it for the last year, especially since about the same time another person started working with the da Vinci robot actuators which use cables to generate find motion. 0.
