Does a brain solve problems? Slime mold says maybe not.
Physarum polycephalum has no neurons, yet it solves mazes —retracting from dead ends, leaving only the shortest path. No thinking, just fluid flow reinforcing strong tubes. Intelligence might just be feedback loops.

@Krishna__Bansal Agree 💯💯
But 95% metric is for ur specific usecase on an average if we consider this metric on a broader this will eventually degrade

[Harsh Singh @harshsingh1804]

@Krishna__Bansal But then the usecase becomes limited and scopes keep narrowing

@prathmak @waitin4agi_ Point bro there can be multiple angles to look at any situation

@codewithpri Why don't guys post something useful or knowledgeable,
Nowadays X is full of this nonsense stuff rather than true content

Ever noticed how apps like YouTube or Instragram keep you logged in for months
—even if tokens expire or your phone is OFF for weeks?

Here’s the secret

Tokens don’t keep you logged in
Device trust does

• Access tokens → minutes
• Refresh tokens → days/weeks
• Trusted device → months/years

What is device trust?
The backend remembers your phone using a secure device ID, app signature, and cryptographic keys — so it knows it’s still you.

When you open the app after weeks: • Tokens expired
• App doesn’t log you out

Backend says:

> “Same trusted device. All good.”
→ New tokens issued silently

You’re logged out only if: • New device
• App reinstalled
• Phone reset
• Suspicious activity
