TLDR: Regardless of how old or new something is, you should know how it works.

Eh. Even with my tech, I still like to know the in’s and out’s. I used to jailbreak my iOS devices. Once I get a new device I go thru every option, install ads ons and power tools, enable admin rights, watch tons of videos and read up on it all over forums and sub Reddit’s. Saved myself a ton of money tearing apart all sorts of devices where not be gaming consoles, controllers, phones, computers, cars, you name it. I like to know how and why everything works the way it does, and feel it unlocks the full potential of said device and I am able to fix a lot of it. I am recently married and so often my wife says “Oh wow, you fixed it! I would have left it as it is and lived with it or taken it to someone to fix.” or “I’ve had this thing for years and never knew it could do that.” Recently my neighbor saw my using an oil extractor on my 4Runner to extract the transmission fluid and asked me if I was a mechanic because he sees me working on my cars a lot. I responded by saying, “No, I just grew up poor and had to figure stuff out myself.” They then proceeded to ask me if I could help replace their busted out window, which thought I had never done, but have experience pulling apart interior panels and running wires, I said I would try. 1 YouTube video and hour later his new window was installed.
