It doesn't really matter what you call it, at the end of the day change happens, and a point will come when when an electrically powered machine can provide comparable results in a comparable time period to a petrol powered machine. When that point comes the only difference between the two will be cost, the cost of purchase, the cost of running, and the cost of maintaining. All of these costs reduce profit, and at the end of the day business is all about profit. If an electrically powered machine can work in a comparable way within areas of the industry then it is a no brainer.
Many will say that that a TM and an electrically powered machine can never be classed as comparable and at present that may be true, however that has been said about many things. It took Thomas Edison thousands of attempts to make the light bulb, but since he succeeded electric light is the main way of producing light. I'm sure many said to him that he was onto a loser, just like people sometimes deride electrically powered machines today. However electric is the future and those who don't embrace change may find themselves in effect holding a candle when they could be switching on the light.
