What is the air quality like to actually breathe in your experience? I have noticed Jakarta on lists of poor AQI and it doesn't look great [1] but I think the AQI number is kind of an abstraction.

I was there ~20 years ago. I had made friends with some Indonesia students in college and joined them on a trip home. We were mostly in Surabaya, but did spend some time in Jakarta as well. We had a great time.
The language is a hidden gem, you can learn enough to get around on the flight over which I can't say about any other SEA language. Phonetic spellings, Latin alphabet, no tonal sounds, dead easy grammar and a million loan words you already know.
Jakarta is definitely for the adventurous though, and you had better have an iron stomach.

Key Facts: Number of megacities, urban areas with 10 million or more inhabitants has quadrupled from 8 in 1975 to 33 in 2025.
Jakarta is now the world’s most populous city, with nearly 42 million residents. The current population of Indonesia is 286 million.
In 2019, Indonesia said it will be moving its capital to Nusantara, a new city which is under construction.

To add some more detail regarding the new capital, Jakarta has some structural governance problems in the sense that it's very hard to improve infrastructure improve / stop the sinking of the city (mostly caused from over reliance on ground water pumping and permitting corruption / bad river management). Those problems might never be solved.
And separate of it's economic power it remains a center of power where the city mayor/governor always becomes a major national political figure.
Indonesia is actually a plurality of distinct island cultures, but with Jakarta, Java and Javanese culture sits at the top of the national political hierarchy. (Not to mention a sort of internal Javanese colonialism similar to the USSR).
The new capital could be part of dismantling some of the legacy internal Javanese power structures.
(To add a further detail re. Java vs. Indonesia, because of the mercator projection it's hard to see how big Indonesia is. It would stretch from Maine, past California almost to Anchorage).

New capitals also help prevent revolutions and uprisings. It's a lot easier to have a government that's insulated from the unrest of the masses, when everyone in its capital is loyal to it.

I also imagine a lot of people who are admiring these megacities have never been to one. Jakarta has oceans of scooters and, when I was there to visit some customers with our country manager, she had a driver. With some exceptions like Singapore, SE Asian cities are horrible to get around.

Other than Singapore. I am not sure why SE Asian cities aren't going as all in on mass transit like China. Jakarta has a single subway line for 42 million people. They have some light rail line and buses. If you compare this with Tokyo, Shanghai, Beijing its really night and day.

Probably a combination of overall wealth and government policies/stability/priorities. I'd probably add Hong Kong to the list of cities with pretty good public transit but, overall, it's pretty bad in that area of the world relative to cities that you'd generally consider to be "good."

Democratic governments are weak on deficit spending, especially poor ones, the debt from their tiny stretch of high speed rail almost became a scandal.

Because Jakarta is literally sinking into the ocean. It also has a terrible flood problem which is only going to get worse. Doesn’t bode well for the population.

I'm always surprised how big the population of Indonesia is yet it seems culturally underrepresented in the world compared to a lot of smaller countries

I also did a double take when I learned that they were Muslim-majority too. It flies in the face of a lot of assumptions.

If anyone is looking for a good movie to get a sense of what Jakarta is like, highly recommend "The Year of Living Dangerously" with Mel Gibson/Sigourney Weaver

Can't speak for the accuracy at the time but great film!

Canada has less people, even with a 10% increase in the last 4 years through imigration, some of which is from Indonesea presumably including a significant number from Jakarta, where the civil infrastructure must be epic

The West just refuses to build anything. Whereas in Asia its not uncommon to build entire cites from scratch.

Why spend billions building when you can just keep raising rents on existing infrastructure?

Canada has been building housing at a much higher rate than the US in the last 2 decades. Not enough, but more.
daedrdev
They have been underbuilding compared to their population trends as we see their prices continue to skyrocket
jeffbee
Hrmm. What data source can I see to demonstrate this? I looked at a chart I have referenced before that shows nationwide USA housing starts over the last 20 years ranging from 2 to 8 per 1000 people. Then I searched for one for Canada and found one suggesting 1-2 per 1000 since 2005. And, evidently, the situation in Canada as developed/deteriorated to the extent there's a whole subreddit for the canadian housing crisis?

Yes, it's easy to build entire cities from scratch in a centrally managed society, such as a dictatorship or communist nations.
It's also easy to have cities grow fast, if you're primarily a rural/agrarian nation, and suddenly have a transition to become urban. This was (for example) Canada in the 1900s. Mostly rural, yet now it's mostly urban.
Canada saw fast growth of cities back then.
It's maintaining large cities once the fast growth is over, that is a different story. How will, for example, China look in 50+ years? 100+ years? When all its newly built mega-city projects are crumbling.

It still does—Vancouver and Calgary have both almost doubled in population over the past 30 years [0] [1].

I used to spend a lot of time in Jakarta for work, and it's an underrated city. Yes, it's hot, congested, polluted and largely poor, but so is Bangkok.
Public transport remains not great, but it's improved a lot with the airport link, the metro, LRT, Transjakarta BRT. SE Asia's only legit high speed train now connects to Bandung in minutes. Grab/Gojek (Uber equivalents) make getting around cheap and bypass the language barrier. Hotels are incredible value, you can get top tier branded five stars for $100. Shopping for locally produced clothes etc is stupidly cheap. Indonesian food is amazing, there's so much more to it than nasi goreng, and you can find great Japanese, Italian, etc too; these are comparatively expensive but lunch at the Italian place in the Ritz-Carlton was under $10. The nightlife scene is wild, although you need to make local friends to really get into it. And it's reasonably safe, violent crime is basically unknown and I never had problems with pickpockets (although they do exist) or scammers.
I think Jakarta's biggest problems are lack of marketing and top tier obvious attractions. Bangkok has royal palaces and temples galore plus a wild reputation for go-go bars etc, Jakarta does not, so nobody even considers it as a vacation destination.
