Earlier quoted context omitted.
I don’t think anyone was suggesting that. Many hackers I know do have other hobbies besides hacking and they devote lots of time to those hobbies. Beer brewing, coffee making, writing poetry, music, languages, … What if one of those hobbies is dressing fashionably? Or makeup? Or whatever? Beyond a certain point activities are zero sum but do you seriously suggest that to be a proper hacker you have no time at all for…
When you are younger the scarcity is money, not time. When I was younger I would have liked to dress fashionably or go out and do more sociable activities , but it was either that or buy computer parts and software etc. I couldn't have afforded both. By the time you get a job that lets you afford both you don't necessarily want to learn fashion from scratch.
Also, computers have dropped massively in price during the last twenty years. I don’t think becoming a hacker was ever super-expensive compared to many other activities, at least not during the last two decades, but now it’s quite affordable. Always depending on what you want to do, but – just as a point of comparison – I think being serious about PC gaming would likely be much more costly (well, I guess equally as costly if you are really into game development or something of that nature).
Luckily computing has never been as affordable and accessible as today.
