It's not good to completely standardize O/S design, since this reduces the gene pool, making most of the internet vulnerable to the same attack. This problem WOULD NOT have been so serious ten years ago. Back then, only a small fraction (perhaps 10% ?) of the internet computers were running UNIX. ARPA hosts were running things like TOPS, TENEX, TWENEX, VM, Level-6 O/S, RT-11, NOS, etc... Sure, it's not a good argument for bashing *UNIX*, but it's a good argument against making *ALL OS's* run exactly the same software. Standardized high-yield crops are a great idea. Until someday, a plant virus or insect mutates, ruins the worldwide crop, and the whole world STARVES. The same goes for computer operating systems.
