Maybe we need to consider WHY the languages were confused at the Tower of Babel. Seems to me that the people were becoming egotistical in thinking they could build a tower to reach Heaven and become equal with God. Was this the ultimate 'smack down'?
Over the years I used multiple db systems and learned multiple dml systems, and I realize now that I never considered it a problem as long as I could have reliable access to the data. It was always a case of doing what was necessary to get the job done. Granted some were better than others, and I did gravitate to the Microsoft vesion as being my preference.
Obviously the tools being used would have drastically affected my choice of a new position during my career, as I suspect most of you would concede. I guess it comes down to how willing we are to adapt to different situations.
I think my greater dissatisfaction is when software vendors make huge efforts to hide and/or limit the access to my data. you've all heard my bitching about this before... One of my software vendors has done this for decades, but I have remained faithful because overall they have the best tool available. On the other hand, I have not subscribed and/or upgraded for eight years because I don't like the directions they have taken. Fortunately at my age and situation, this is a viable option.
