apropos of nothing nautical, every time that I read the expression plug and play I shudder. Up until very recently I still had my old Windows 5 computer complete with WordPerfect (still the best word processing programme I have found for creative writing). We are now on Windows 11 yet if you compare the two, most of the improvements have been designed to create obsolescence not ease of function. Yes it is faster but the computer's taking over certain functions from me have made me dumber not more efficient. The same is true of many of the more recent auto improvements to the point where care mfg. is going back to more basic installations. Perhaps our military purchases are reflecting the same trend: adding tech. where it isn't really necessary that will make maintenance and repair more difficult and make the equipment more vulnerable to failure.
