You're right, we're moving forward at a steady pace. I bring my experience here. I started working in an office as a designer in 1996 and we used pen and graph paper for drawings, then in 10 years, we moved on to drawing or designing machinery with two-dimensional CAD software and then in 2005 we started using modelers three-dimensional. We don't realize it, but progress is going so fast in these last decades that we almost struggle to keep up with it.
