I can answer this- at the time I joined GOogle, my goal was to use their resources to enhance my future career as a researcher. Google gave me access to world class hardware, software, and employees, which I could use in ways that never would have been available at any other location. It helped me build and achieve a system that academia would not have allowed, that I could not have done on my own time and money.

But my goal was always to take that newly learned skill and credibility and use it to go back to academia with a stronger hiring position. I mean, that's the mental model nearly all scientists have: couple your job with your interests to maximize your impact using other people's money and time.

i imagine because you’re required to be present in some sense for ~8 hours a day 5 days a week. that doesn’t leave much time for anything else, especially if you have caring responsibilities or any other life commitments. once you’re in a depressive state getting out of that hole can be a real struggle

The short answer is I tried - for about three years. Meanwhile, I had the onset of depression, panic attacks, and numerous other physical ailments. It's taken about two years of therapy, but I've finally realized that I am just not the person that can do that.

Funny enough, I have a co-worker who is able to perform in this way and he appears to have no issues with the current status quo. As much as I might wish I could be more tolerant, I've accepted that I'm just built different and I need my job to provide a challenging environment.

Why not both? Work is ~40hrs a week, so it's nicer if you have the option to enjoy it. There are other software jobs with similar pay to Google, but with more rewarding work. Win-win to switch, if that's what you're looking for.

Personally, the type of problems I solve at work are more interesting than I could realistically come up with and work on on my own. Ymmv.

This is how govt employees treat their jobs in various countries. In the private sector, there is no job security. What happens when one gets laid off with rusty skills? That's why folks want to use the existing job to improve skills. That explains why people want to use new frameworks, tools, languages at work.

It's exhausting being mentally present while knowing you're not doing anything useful. Using that time to actually work on side projects feels very unethical, so it's kind of just going with the tide for 8 hours a day then being exhausted at night. So the challenges I found were usually in games, not anything productive.

I have far more energy now that I'm actually productively working in a new job and seem to have lost a lot of interest in games as a side effect.

It takes third of the lifetime. It's massive waste of time and energy if you get only money out of this.

Usually, jobs with challenges pay more. I switch jobs if both of these conditions are met: a) good enough challenges, b) pays more than current job
