Physical AI long-tail cases are such a major problem in ML that people don't even perceive the pain: "it just is".
You launch 100 agents in parallel to test different setups and, in the end, pick the best results. But doing so, you just rendered 99% of the computation useless.

Why is this not a thing?

[Alexandru-Andrei Rotaru @rotaruzaurul]

@NikolausWest People vibe train some shifty vla, benchmark it to 72% then call it big research, worth the money invested. 100%

[Alexandru-Andrei Rotaru @rotaruzaurul]

@b1rkh0ff I let the model used my hand to do stuff...

[Alexandru-Andrei Rotaru @rotaruzaurul]

@haider1 @b1rkh0ff Code better than most devs... The top 1% of devs code better than most devs 99.9999% of the population is absolutely trash at any given specialised task. My point is that, the tech is good an useful, but let's not hype it out of proportion.

@simon_zhai Seems like a toxic relationship

[Alexandru-Andrei Rotaru @rotaruzaurul]

@SemiAnalysis_ @AnushElangovan I think none of these would be necessary if we had a better way to develop these

[Alexandru-Andrei Rotaru @rotaruzaurul]

@swyx I understand none of those words. Can you tokenize them pls

[Alexandru-Andrei Rotaru @rotaruzaurul]

@pmddomingos Buttthurt "scientists" incoming

[Alexandru-Andrei Rotaru @rotaruzaurul]

@pmddomingos This i sulting people religion. Bigger benchmark number is always better. Must be.

[Alexandru-Andrei Rotaru @rotaruzaurul]

@pmddomingos Noo. Its weirghtslab

[Alexandru-Andrei Rotaru @rotaruzaurul]

@droidbuilds he is right tho, most people with laptops are "takers" rather than "givers"

[Alexandru-Andrei Rotaru @rotaruzaurul]

@zack_overflow Come on, Opus, it's not really smarter than you. It's like saying a hair comb is smarter than you cause its better at tasks than your fingers.

[Alexandru-Andrei Rotaru @rotaruzaurul]

@hthieblot Founders are never wrong. It's almost always the market. Even Steve Jobs and Henry Ford thought this.

[Alexandru-Andrei Rotaru @rotaruzaurul]

Agentic automation is starting to feel more like a religion than a science.

[Alexandru-Andrei Rotaru @rotaruzaurul]

@samir_sawarkar agents are a religion now, not science

[Alexandru-Andrei Rotaru @rotaruzaurul]

@lukas_m_ziegler he si 100% right.

[Alexandru-Andrei Rotaru @rotaruzaurul]

@Henryf1w yes. you are ugly.

[Alexandru-Andrei Rotaru @rotaruzaurul]

@yacinelearning Not really, but it does not really matter. You can stilll have quality data and quality models, and compensate.
