Nobody is decrying the use of new technologies such as the electronic symbol and icon status and alarm systems. The new systems also have enormous flexibility in their designs which can, if used in a poorly thought out fashion, be a very serious problem for the users. All technologies have their good and bad points. Unfortunately, many designers and engineers often use these technologies, because they are there, in a design format and in a manner that is inappropiate and at times, downright unuseable for a good proportion of their customers. They simply do not think through how these technologies may have to be used by the customer. That is the thrust of my argument. I am very surprised by the comment on no further development for an aging work force. As of 2007, one half of the world's total population will live in the cities. This comment reflects the attitude of a majority, particularly in the western world, of those city dwellers, that agriculture is finished! Please tell me, just what in the bloody h-ll are you going to eat if that is the case! Or do you, as some of these city dwellers believe literally, that food is just created on the super market shelves. Enjoy your very cheap food while you can. There are a number of major think tanks around the world that are calling our current food surpluses a "food bubble". The world, for the first time in the human races history has been able to comfortably feed itself only over the last 100 years. longer term, say by late in the next decade, the think tanks are starting to get very nervous about the world's ability to continue to feed itself adaquately. There are a lot of very serious long term problems in the world's food production systems that are only now starting to show up. So, instead of swallowing an oft repeated mantra, before condemning the whole agricultural industry to it's deathbed and making statements that nobody is going to bother to develop new technologies for an aging industry, I would suggest that a little research be done first. Cheers.
