I'm curious, in what niches are people using Swift for new applications these days? I've enjoyed working with Swift in the past (albeit in very limited capacities), but I haven't personally come across any Swift-based initiatives in a while. I had high hopes for Swift for TensorFlow, but it was ultimately killed off.
"Will the AI be smart enough to realize the unnecessary bits, or are you just going to layer increasingly more levels of crap on top? My bet is it's mostly the latter, for quite a long time."
Dev cycles will feel no different to anyone working on a legacy product, in that case.
YMMV, but I've found anecdotally, that qualitative aspects of my sleep have an outsized impact vs. the # of hours, to a point of course.
For instance, in my teens/early twenties, I (like many) was able to sleep quite a bit less. Lots of late nights traipsing around the internet, lots of midnight projects.
In my mid-twenties, I suddenly found that I needed much more sleep. If I didn't get at least 8 hours, I woke up completely drained. Other adults I spoke to confirmed that this was normal.
Then, I switched apartments and got a new bed. Suddenly, I was waking up much easier, even with few hours of sleep.
This pattern has repeated a few times throughout my life. I'll notice I'm waking up more tired than usual, and then something will change—a new room with more natural light, a better mattress, the loss of something I didn't realize was stressing me—and I'll suddenly need less sleep.
I'm sure none of this is shocking to anyone, but the key thing for me was that even when my sleep quality was apparently deteriorated, I didn't notice it. I still fell asleep easily, I still had dreams, I was still comfortable in my bed, etc. The sleep cycle, it seems, just wasn't as restorative due to other factors.
I have a little pet theory that some of the "Super CEOs" we hear about who get by on 4-5 hours of sleep a night are:
1. Slightly exaggerating the rigidity of their superhuman schedule (I used to work in media, and I've worked with an outsized number of people who have public reputations for this kind of stuff. Anecdotally, I've found that nearly all exaggerate and sometimes outright lie.)
2. Adept at compartmentalizing stress and environment, to the extent that they're able to get quality sleep regardless. This skill would naturally track other responsibilities in their life as well.
