I've only been saying every circuit should be built this way for 10 years. they have known the advantages for years, but they don't want anything to last forever, they want u to keep buying new ones. if this is done right u would be able to switch the bad circuit without ever turning off or interrupting the circuits tasks. it will be awesome to be able to fix things before they break completely and without shutting them down for maintenance.

??? WHAT ARE YOU TALKING ABOUT ??? circuits have no need for error correction they are hard coded by being physical to beahve exactly the same way with voltage and current.

error correction in the classical sense is for fixing misinterpretations of variing voltage in a circuit as it applies to logic carried out by a processor like system.

I think he is mistakenly interpreting "error correction" as "self repair".

"Error correction" is where you have extra circuits which double check the work of the first circuits, or else the first circuits re-do their own work to double check it.

"Self Repair" is currently non-existent in computer technology, at least to my knowledge. This would require some form of nano-assembly.

Error correction is required in digital systems due to electrical noise that can cause logic circuits to switch to the wrong state.

Error detection in logic circuits is typically implemented using an even/odd parity bit that allows single bit errors to be detected. When an error is detected the circuit typically stops and requires a reset. In more complex logic circuits like CPUs, an error may trigger an interrupt that executes error handling code. Logic circuits are very reliable and single bit errors within the circuits are rare. Consequently, in this case, the cost/benefit ratio of error correction is unfavorable.

In a digital communication channel, a cyclic redundancy check is used. A CRC allows both detection and correction of multi-bit errors and is efficiently implemented in communication hardware. Communication channels are generally not reliable and it may not always be possible or desirable to re-transmit a message. Consequently, Cost/benefit ratio is favorable.
