Why are modern manufacturing techniques preferred over those historically used by artisans?

Manufacturing through machinery allows for below advantages,

1. Reproducibility - Achieving close to same results is higher.

2. Productivity - Saves time, produce more in quantity and could cost less as materials is saved more.

3. Consistency - Consistent as the method is replicated to a better percentage than manual method.

4. Precision - Use of machines in manufacturing allows for precise measurement of parts.
