I still believe it's relatively easy to find high quality material, even for amateurs. For example, I can watch live train yard cams nowadays on Youtube (Virtual Railfan on Youtube), and watch people who know what they are doing do live coding. I'm definitely losing myself in a multitude of options but I won't balme it on the accessibility of modern Internet.

20 years ago there were definitely less garbage on the Internet, and less gems as well.

But I definitely agree with the movie part. We still get a few good ones here and there but it's kind of rare nowadays :(
