AI-powered debate arena where you compete and receive skill ratings for your argumentation.
u/Bakari2Sense · Reddit
Built a persistent skill rating for debate, like a chess rating but for argumentation I built a persistent skill profile for debate called the Debate Fingerprint. Would love feedback. [Founder disclosure: I'm Bakari, building 2Sense at app.2sense.ai] The idea: every debate you complete scores you across 6 dimensions (Logic, Structure, Responsiveness, Persuasion, Emotional Control, Clarity) on a 0-1000 scale. The scores persist across all your debates and build a visual profile over time

Direct link to extension (the site just gives you more context): https://chromewebstore.google.com/detail/sphinx-earn-your-di... Philosophically it's a speed bump rather than a hard gate, because you'll eventually tear a gate down but you'll leave a speed bump. I've always eventually removed site blockers, or just had them become a nuisance that I reflexively dismiss before getting to distracting sites. Site blockers don't really reduce the "start navigating to a distracting site" muscle memory, and they eventually just become annoying. Dopamine is a hell of a drug. At the same time, I've been getting frustrated that my intermediate/advanced math skills have atrophied, and becoming more senior in my career (plus AI...) has caused my coding skills to atrophy even further. Realistically I'm not going to force myself to do math or coding exercises aft
