It is very common for the normal lay-people to catch up with the advances in science and professionals several years (even decades) after discoveries are made. For example, scientists have been using microscopes and telescopes for centuries. Right now, I could leave my computer and go to Walmart and buy a decent telescope and a lesser quality microscope.
The army has been using Hummers for 50 years. Only in the last 10 years have consumers been able to buy hummers.

Now, chefs and professional cooks are no longer going to have the advantage. These kitchen professionals have been using kitchen scales and specifically digital kitchen scales. These different tools allow us to measure ingredients with amazing precision. If you have never used a digital kitchen scale you should try one out. Instead of wondering if you squish brown sugar in the cup measure, or if you really did put in the right amount of cups; you can know exactly how much you put in and can even have ease in reproducing the same recipes.
