I had to click, because it turns out that I love soldering. It's relaxing and has a skill curve such that there's a trick to it but with a bit of practice, you can be someone who is really good at soldering, too.
For anyone reading, the key is to invest in a proper stereo microscope and a decent fume extractor.
If you don't have space for a microscope, you can also get yourself the long-range (~400mm) 2.5-3.5x magnifiers that you may have seen your dentist wear. They're easily available on Amazon, not too expensive, and comfortable for hours of wearing. These are 2-element lenses that work really well.
Higher magnification variants (8x etc) are not nearly as comfy. They get quite long, heavy and expensive. I tried them and did not like them nearly as much. Also beware of short viewing distance, ultra-cheap products that are just a single lens element per eye.
The new breed of irons with temperature measurement built into the tip (invented by JBC, cloned by Geeboon and similar) is amazing. The tip heats to exactly the temp you want in 3 seconds, then cools down to avoid damage when you put it back in the stand. As you solder, the power is automatically controlled to keep the tip at the specified temp regardless of the load you put on it. I never thought I'd replace the Weller station I've used for 20 years, but I'm glad I did.
I have a Hakko FX-888D. It's pretty good, although I wish there was some way to switch tips that didn't involve letting it cool down to a safe handling temperature.
I am curious what you mean by rework tweezers. Link please!
I go through these for solder flux removal like crazy, in combination with an aerosol can of MG Chemicals 4140-400G. Sadly, I think that stuff is unobtainium now.
I swap the tips on my Hakko without letting it cool down, I just use a Knipex pliers wrench so I don't burn myself. I keep my spare tips in an altoids tin, so I can drop the hot one in there without burning anything.
Depends. The ancient Weller that I have has a sleeve you can unscrew but that sucker gets burning hot, and the thumbscrew locks up unless you cool the tip down, which you can do by holding the thing on your wet sponge.

I don't know. I've got my station, not a bad one: bought it with the help of a buddy who's very good at soldering. He tried to show me. I've got no choice: I own an old vintage arcade cab from the mid 80s and it's located in the middle of nowhere, in a rural area. So I have to fix it myself.
And oh boy do I suck at it. I watched vids, countless Youtube vids. It's been 10 years and everytime I need to solder something, I still suck at it.
I've come to terms with the fact that there are some things I'm good at and that soldering is never ever going to be one of these. And it's okay.
Everything is lead-free surface mount now. Solder paste, stencils, reflow ovens.
Hand soldering is precision temperature controlled irons, hot air rework stations, magnifiers, cameras, and exhaust fans. The tools are more complicated, more expensive, and better.
One of the lessons of surface mount work is that you really can move your fingers a thousandth of an inch. But you need magnification to see what you're doing.
I'm encouraged to see more hobbyists going surface mount. In my TechShop days, I was the only one doing surface mount. Everybody else was using 1980s 0.1 inch spacing DIP components. That's a US thing. If you learn to solder in Shenzhen, you start with surface mount.
I love soldering, even though my skill ceiling is SMD components. There is something almost spiritual and humbling about soldering because you cannot force your will onto the solder, you have to listen to what the solder wants to do and work with it, not against it.
When I first tried my hand at soldering I was using the "butter knife" method: apply solder to the iron, then try to smear it onto the wire like spreading butter with a butter knife. Of course the solder would never stick to where I wanted it to go. I had to learn that solder goes to where the heat is, so I instead had to heat the components or wires instead and then feed the solder onto the hot components. I also had to learn that a soldering iron is not a pencil, sometimes even when doing small parts you want to use the large tip. Don't try to tell the solder where to go, instead apply a big blog and watch it snap into place on its own.
Last year I installed an HDMI mod[1] into my Wii, this has been so far the hardest project. It took me many attempts to get it right, mainly because I was working against the solder instead of with it. But now that I have succeeded I could easily do it over and over again (not keen on the disassembly and reassembly of the console though).
EDIT: while I'm at it I might as well mention the iron I was using: the Pinecil[2]. It's a really neat and fast soldering iron at a very cheap price. Great for people like me who don't want hardware store cheap garbage, but also cannot justify buying an entire soldering station.
I feel like this poem isn't really about soldering, but if anyone is actually bothered by it, there are some options.
Unleaded solder and a decent fume extractor make the process cleaner. A decent soldering iron and solder wire with good-quality flux (e.g. Kester) makes it faster.
If you'd rather not deal with the iron, you can manually apply solder paste and use a hot air rework tool or even a heat gun (careful!) to melt it. (A proper reflow oven is better, of course, but that's pricey.) This makes working with surface-mount components much easier.
If you'd rather not deal with it at all, have a PCB assembled somewhere else. JLC is pretty cheap, especially on simpler boards.
To each their own. I find soldering (with a nice iron!) very therapeutic, much like knitting. I'll put on a good album or catch up with some friends on the phone.
If you're impatient, plenty of fab houses (like JLCPCB) will do all the soldering for you, for about 0.1 cents per SMD joint or 2 cents per THT joint...
Soldering is fun, especially if you designed the circuit and the pcb yourself. It's like putting together your own frankenstein, with a huge amount of anticipation toward when you finally get to give it power. Just be sure to get the polarity right on those electrolytic caps ;-)
When i was in college I was soldering something really small (don't remember what it was) and flicked molten solder right in to the tear duct on the inside corner of one of my eyes. Not fun but didn't hurt anything permanently.
I hate to say I love the fumes - that rosin smell is unique. Did many soldering projects in an enclosed area back when I was a kid. Everyone worked that way years ago. I wonder if the fumes kill more people than being neurotic about the fumes.
I had a friend that taught with leaded solder and say 'you can wash your hands, but you can't wash your lungs', and considered the fumes from lead-free solder as more exotic and cancerous than burning rosin. Lead free is regulated to prevent the metal from getting into the environment on a large scale, there's not health regulations around what gets burned off when hitting lead-free solder with a soldering gun at the wrong temperature. It's meant to be cooked in an oven with ventilation away from humans.
I disagree, it’s a joy actually, shame that jobs that involve soldering don’t pay well, yes, even embedded engineers aren’t paid that well plus soldering is less than 10% of the work.

I recommend this one: https://www.strangeparts.com/a-boy-and-his-microscope-a-love...
If you're up for a bit of a bonus round, I absolutely love my Pixel Pump. https://shop.robins-tools.com/products/pixel-pump
I picked up a used Ninja toaster oven and hacked a https://reflowmasterpro.com/ to it. I also modified the plans for Stencil Fix to make it substantially bigger: https://www.youtube.com/watch?v=Am3ztQIkss0
So, I do a fair bit of both reflow and hand SMD soldering at this point, depending on what the situation calls for. It's great fun.

Me too I love soldering. And actually, it's one of the few things that I like more and more, as I realize I've developed a real craftmanship from it.
And thank you! I've been looking for a recommendation of a stereo microscope for a long time!
Agreed on stereo microscope, also suggest flux and a good iron with exchangeable tips and rework tweezers (I enjoy the Hakko).
The new breed of irons with temperature measurement built into the tip (invented by JBC, cloned by Geeboon and similar) is amazing. The tip heats to exactly the temp you want in 3 seconds, then cools down to avoid damage when you put it back in the stand.

Share a link! Don't be shy.
I can't imagine not using flux!
I have a Hakko FX-888D. It's pretty good, although I wish there was some way to switch tips that didn't involve letting it cool down to a safe handling temperature.
I am curious what you mean by rework tweezers. Link please!

I replace tips while hot: the sleeve is not hot.
Depends. The ancient Weller that I have has a sleeve you can unscrew but that sucker gets burning hot, and the thumbscrew locks up unless you cool the tip down, which you can do by holding the thing on your wet sponge.
Step 1: Have a workshop space Step 2: ? Step 3: Profit

He's soldering like it's fifty years ago.

I enjoy soldering, and like your comparisons. Yet I certainly don't blame the author for highlighting how unhealthy it is.
Nice iron,a good clamping set-up, and a high-quality correctly specked (to the task) solder make all the difference
Soldering is fun, especially if you designed the circuit and the pcb yourself. It's like putting together your own frankenstein, with a huge amount of anticipation toward when you finally get to give it power. Just be sure to get the polarity right on those electrolytic caps ;-)

So get yourself a solder fume extractor? There's plenty cheap ones to pick from.
Watching skillful SMT soldering on YouTube fascinates me in a way that helps me understand the ASMR videos that the kids watch these days.
Recommendations?
No particular channels or videos come to mind, but here are a couple good ones (with timestamps to skip the intro fluff):
https://youtu.be/0LSG5uIdqJc?t=190s https://www.youtube.com/watch?v=wUyetZ5RtPs&t=40s
I would not call 2nd video "skillful", that SOIC was molested, not soldered :(
Fair enough, perhaps I'm easily impressed. :)

Yeah I grew up with it too. Also the smell of cigarettes and coffee typical of so many communist government offices brings back pleasant memories.
