If you have a better way, you should patent it now.


I don't, but that's beside the point. Unless you can show that computers
can only be made out of semiconductors (highly unlikely), you cannot use
semiconductors in an argument about the general applicability of binary
to computers.

Yes, really. Diesels have cheaper lifecycle costs.


It depends very much how they're used. Diesel engines have a higher
capital cost. They're only have lower total costs if they're used a lot.
Otherwise the cost of capital is more than the lower cost of the fuel.
