There are a lot of very complicated projects that in times past people would need to farm out to a trained technician or professional. Now, they can just hop on the Internet, read an article, watch a video, or listen to an audio program and learn how to perform even the most complicated processes in a step-by-step manner. For example, if a person wants to replace the alternator on their car, they simply need to type in the type of vehicle they have, the type of alternator they have, and they will be presented with a whole host of do-it-yourself videos showing them every single step they need to take.
In addition to the step-by-step videos, there are also comments where people who are novices just like them ask questions about the problems they have encountered. All of this has taken the fear out of doing complicated home repairs or electronic repairs.
In addition to saving people time, these do-it-yourself videos give people the confidence they need to do more things for themselves. They also encourage people to get interested in areas that they were not interested in previously. For example, a person who only has a passing interest in electronics may have an electronic device that fails. They call a repair person to fix it, only to find that the cost of repairing the item is more than what the item itself is worth. So they hop on the Internet, they look at a how-to videos, purchase the parts they need from Siemens electrical distributors, and they fix the problem.
Once they realize how easy the repair was, they get interested in learning more about electronics. Instead of going online to watch videos about how to repair products, they are the ones uploading videos explaining how repairs work. All of this is possible because of the power of the Internet. Truly, the Internet has been a force to change society for the good.
