This is a very interesting topic.
I believe there is no correct or wrong answer to the question raised in the initial post. There are, as you can imagine, several points for and against either argument. For example, it is obvious that technology can help improve quality control, measurement and control aspects of cricket bat making. However, it is universally agreed that the best bats are hand-made. Then, why is there room for machines and new technology in the world of bat making? Probably because most people try to find a balance between cost and the podshaver's skill.
Theoretically, a machine is more precise than a human (mostly) and new technology will probably make the bat-making process more efficient, cheaper and quicker. However, machines arent and never will be as intuitive as the best pod-shavers. This is key in my opinion. Like my fellow poster said, having Tendulkar's bat in one's hands will not make them as good as Tendulkar at the crease. That's not to say that Tendulkar uses the best bats. After all, his bat might not be good for say...a Matthew Hayden or a Luke Wright.
The best bats I believe are made by pod-shavers that can match bats to individual players perfectly. Technology will never be able to help that step of the process.
The bottom line, imo, is that technology can definitely help in the manufacturing side of things for mass-produced bats....maybe even hand-made bats (by providing better tools etc), but will these 'improvements' help produce more perfectly matched bats for people like you and me and the pros, or improve the playability of the bats? I dont think so. However, there would definitely be people who think otherwise and I'd love to hear their views!
The best part about the world of cricket bats is that, after a certain point, its all very subjective in nature.
