Is any sizable portion of these jobs interchangeable with deep learning?
The best deep learning engineers with infinite hardware built Amazon’s recommendation algorithm, and it’s largely trash. I can’t imagine it’s magically thousands of times more capable for these other tasks.

What is trash for you may not actually be reflective of how good the algorithm is. My experience is that Amazon's algorithm actually works somewhat well.
Recommendation algorithms usually work well for people who are closer to average (i.e. their preferences being closer to the aggregate). People who deviate from the average tend to get poorer recommendations. It does even worse for segments that deviate so far from average where there are few sample points.
Recommendation algorithms optimize for aggregate conversion -- if it can get the most number of people to convert, it is good (for the merchant) even if it looks like your personal recommendations suck. It's all a matter of perspective on what "good" is.
Something I did as I did when younger that annoyed more ambitious friends: go to Wikipedia and find the incoming freshman class size for the top schools (say Harvard, Yale, Princeton, Stanford, MIT). Add them together. Now look up the number of high schools in the US and assume there’s 1 valedictorian per school. There just aren’t enough spots to even fit them.
Now complicate things more: all the elite high schools like Groton or something are gonna be sending way more than their top 1 student to these programs.
My conclusion was that it frankly doesn’t matter how much you compete with your personal classmates unless you have some other angle.
However outcompeting your classmates might get you a full scholarship to the state flagship, which is actually massive if you don’t use it completely imprudently.
I can’t imagine any circumstance other than a Ph.D program where someone spends 5+ years studying in depth some tiny area of science and practicing research. And without doing that I’m having trouble believing almost anyone will do serious research. There are a few people who did it but to me that is extraordinarily unlikely.
Agreed, those people are few and far between. Even if your job is fairly stable, you'll more likely work 'around' a problem more than a deep dive into a very specific problem.
It probably wouldn't. But that isn't the question here. Look at what the OP wrote:
I'm shy and I feel weird talking to people, looking into their eyes. Talking to a group of people will make my voice shaking and I feel inferior and less confident whenever I talk to people
That isn't a sales problem, that's a basic, fundamental issue of confidence, self-assurance, "frame of mind", or whatever you want to call it. If you can't even look at people and talk to them, you're not "doing sales" yet.
What weight-lifting and jiu-jitsu can help with, in my (admittedly anecdotal) experience, is that "confidence, self-assurance, etc." stuff. The stuff that's a prerequisite before even getting to the actual sales part.
Since I don’t live in a dangerous area or work as an MMA fighter that stuff wouldn’t help me. Frankly my opinion of what’s scary about people is self-centeredness, social connections, whether they have willingness to throw me under the bus for their benefit, etc. No help from jiu-jitsu unless it makes them bond with you. Or maybe a (my opinion) small but noticeable positive benefit looking athletic can give you.
As an employee I’ve felt like it’s hard in the past to take initiative and do things that aren’t immediately and clearly justifiable as strictly necessary work. Reading a book might or might not be useful but doing something boring but mandatory is certainly not slacking. With that said any time I tried to take more initiative and take more risks (while making a sincere effort to work on the thing that’s going to move the group/project forward) and then just accept correction if I make the wrong call, usually work was more enjoyable and I was more productive (by estimation of me, other coworkers, and my manager).
What would it even mean to have a romantic relationship without attraction?
Why do people bother dating if it’s sufficient to move in with a friend?
How do we explain people who already live with close friends and are also out seeking romantic partners? What marginal benefit could they be looking for? Why limit the search according to gender, if attraction is not essential?
