No we wouldn't. We're around ~10,000X off and would run into thermal danger zones long before.
- IIAOPSW 9y agoBUT....The Launder limit is over optimistic because unless your computer runs at absolute zero you need to keep redundant copies of each bit for error correction. Transistors are implicitly error correcting in the sense that each bit is represented by a current of a few thousand electrons. Factoring in the redundancy requirement we are likely only off by somewhere between 100x and 1000x. If there were ever a return to exponential technological improvement, we would run out of road after a few years.
- deepnotderp 9y agoThat's my point though, the bottleneck is not going to be Landauer's Limit.
