Politicians don't like boring pragmatic ideas, they like cutting edge new things. You see it all over. Building a fancy building when a boring box would do. Building expensive trains when a cheap bus would do as well. Investing in cutting edge tech of all types when the existing technology already works perfectly and we have no reason to think the new will be better. Don't get me wrong, there is a time and place for fancy buildings, trains, and cutting edge technology, but politics often invests in the above when there is no reason to think they have a place just because it looks good.
