MIT energy-efficient transistor is a lie.

spintronics is deadend

Energy-efficient magnetic transistors are fake news.

Deadend quantum mechanical spintronics (and universities ) needs overhyped fake news on useless transistors.

(Fig.1)  a very bulky, energy-inefficient useless transistor needing cold temperature (< 70K ).

Energy-efficient compact magnetic transistor hype.

Researches on transistors, spintronics are deadend due to useless quantum mechanics that needs overhyped fake news.

The 2nd, 6th-last, last paragraphs of this hyped news (9/23/2025) say

"MIT researchers have now replaced silicon with a magnetic semiconductor, creating a magnetic transistor that could (= just speculation ) enable smaller, faster, and more energy-efficient circuits"  ← fake news

"They use an external magnetic field to change the magnetic state (= irrelevant to spin ) of the material, switching the transistor using significantly less energy"  ← fake news

"the researchers plan to further study.."  ← still need more research, so useless.

A very bulky useless transistor contrary to hypes.

This new useless bulky magnetic transistor needs very cold temperature, which is very energy-inefficient, contrary to fake news.

This research paper ( this ↓ )

p.15-Fig.(a) shows this magnetic transistor is far bigger and bulkier (> 3000nm, from scale bar = 500nm ) than the current compact electric transistor of only less than 50nm

p.15-Fig.1(c), p.16-Fig.2. p.17, p.21 shows this magnetic transistor must be operated at extremely low temperature = 70K, which needs more energy.

↑ Needing extremely low temperature means very energy-inefficient, contrary to the above fake news hyping "magnetic transistor that could enable smaller, faster, and more energy-efficient circuits"
