I mean, gaming is my hobby. Compared to shit my colleagues do with gambling, poker and BS, that's a cheap AF hobby.
Like a guy here downed $2k USD one day on a poker game that did not go well, he joked that his wife will make him sleep on the street next 3 days. And it won't be his last. That's like money gone poof... compared to that 3080Ti you at least get to enjoy for 3 years or so.
Another guy spent good $10k USD for boating lessons and captain license, because he wants to lease a small boat to take on a self-made cruise in Mediterranean.
And it's not like we're some giga investors and billionaires, plain run off the mill devs working for some fintech corp. It's a shitty work with occasional crunch/overtime and we're doing stuff we like to unwind.
