The more I learned about chess, the less I wanted to play it. It's a beautiful game (the perfect game, according to some). But it has way too much memorization for me, and software has left human players in the dust.

For me it was magic. I love watching magicians. When I got a chance to do some magic tricks it just wasn't as much fun as watching someone else do them.

How much knowledge?

The expression "to learn how the sausage is made" is almost ancient, but not every subject is a sausage factory.

Depends.

There’s a reason I wouldn’t suggest monetizing your hobbies. It’s okay if you suck at a hobby.

For me, 3d printing is a blast because it’s always growing, doing more things. I started in my teens; late 90’s. It wasn’t a thing in general discourse, my printer was literally a hacked-up Lexmark inkjet I bummed off my dad*, and a hot glue gun I bummed off my mom (I don’t think she even noticed…).

I’ve gotten to see the hobby grow from a pipe dream where commercial machines cost more than a small house to accessible to most adults.

Back in 2010ish, I realized my retirement 401k was sucking- I was actually loosing money (thanks 2008,). So I started a company in that space. ( no, it wasn’t another print farm, exactly, but the bread and butter service was actually leasing printers and maintaining them- like xerox machines.) it’s always been a side gig even if people think I’m crazy.

In any case that has sucked a lot of the joy- and I constantly have to remind myself not to be that asshole ragging on the new guy cuz they got spaghetti prints; or shitting on entry-grade printers because they’re not industrial grade. (There was that one asshole in my life that caused me to shelve it for a long while.)

But, also,’there is a lot of new things in the space, even in FDM printing and it’s just wild what’s being done.

*in my defense, he gave the printer to me. It was a freebie from a pc bundle and he didn’t need it. But like a year or whatever, he needed to print color and got really confused as to why he couldn’t print out a single page. My mom still finds that exchange to be hysterical. I’m pretty sure she still hasn’t figured out where her hotnglue gun went…

For me it's per activity and how you get your fun from it.

Like for example, in a game of hide and seek, the fun part is exploring and finding where people hid, if you already know that then it is not fun anymore. This kind of activity lines the same as with reading books or watching a movie.

On cooking, it is a different kind of fun because the more you know, the more you can apply. Medicine people have the same tendencies as well as athletes for these.

There's also the type of fun you get with jokes, or for music.

Other people's mileage may vary as each have their own approaches to different activities.

it depend of the subject, i'm still enthusiasm about computer stuff and want to keep learning

You mean life? Yes.

It depends what makes you tick, and how much you care about a particular thing.

If you like learning a lot of superficial to mid-level information about a lot of things, diving too deep will naturally result in a loss of enthusiasm, and that’s ok. You only have so much energy for each thing to take.

But if you really enjoy doing a deep dive into one or two things, more extensive knowledge is the best reward for the effort, so it’s a self-reinforcing cycle.

I’ll never be the latter person. I’ll never know all the lore for anything, or know every model of machine or whatever. That’s not what makes me tick. I do tend to get bored when I know too much about a thing and learning more means engaging other people’s thoughts (books/media), or using math, or whatever boundary I don’t feel like crossing. But that’s ok, my enjoyment is from knowing a lot about a lot, not from knowing everything about a few things. Both are good and valid.

I think it's just that eventually enthusiasm wanes. Look how many people were wild for the Marvel Universe and how many are bored with it now.

I was a game developer for almost 20 years, and I made so many games that it reached the point where I just realized, there is literally nothing left to learn, I have "done it all".

I started in the day when there was no tools to make graphics, if you wanted graphics you first made a drawing program.

Eventually it became insanely boring and tedious to me. Sure, technology kept changing, but the underlying challenges were long solved.

It depends if it is impressive that you know how they do things or that you don't know.
