Re: I can't stand this nostalgia junk recreating junk.
Those YouTubers sound to be like they're exercising their electronic diagnosis and repair skills in pursuit of a tangible goal, while providing a record of what they did that might help to improve the abilities of others. It doesn't sound any less reasonable of a way to spend time than e.g. working on an open source project which likely won't ever have more than a handful of users. It's also a thousand times more interesting than the usual YouTube stuff of people recounting or enacting perfectly ordinary events as though they were Beowulf, pausing only to gurn.
