The 737 was designed using light tables and slide rules, to use low-bypass turbofans and direct controls with avionics only on board to optionally aid the pilots.
The A320 was designed in CAD and using CFD, with full digital fly-by-wire, and designed from the start for high-bypass turbofans.
Both designs have been updated plenty since, but because the basic design is much more modern, the A320 is much more amenable to being updated. There are elements of the 737 design that still exist on every new MAX coming off the line that would completely doom the certification chances of any new design, but are still there because they got grandfathered in for 737.
The wonder is not that the A320 finally caught up in sales, it's that the 737 can still be legally sold.
What’s wrong with the 737 design that it wouldn’t pass today as a new aircraft? (Ignoring the disaster that was the MAX.)
So you have to constantly apply some controls to fly, done by software.
I love stupid car comparisons so imagine a car with a new engine that is more economical to run, but very heavy on the left so the car constantly want to turn left. But if you apply force to the steering wheel manually or the car does it for you with software, all good. Still a shit car though.
I think they added redundant sensors which should theoretically prevent this in future. IMHO, I think several issues compound here. They should have redesigned the fuselage. The engineering compromise is bad, but if handled with care, could have been done relatively safely. They opted for no additional pilot training re MCAS. This was a fatal mistake, compounded by them relying on a single sensor. Nothing in avionics relies on a single sensor for remaining in the air. That was insane. There MUST have been engineers screaming about safety who were ignored.
Not only that, but Boeing is actually limited in how much they can "modernize" the 737, because doing too much might exceed the limits of the 737's type certificate. This is the reason behind the current engine inlet overheating worries, which has led to an airworthiness directive for the 737 MAX (https://aerospacenews.com/faa-airworthiness-directive_boeing...) and is also one of the reasons for the delay certifying the MAX 7 and MAX 10. This would be a complete non-issue for other planes, because all modern designs have a switch position that only turns on the engine anti-ice system when it's needed, but the 737 MAX can't have that because the 1967 737 didn't.
(Was on a transatlantic one once. Never again.)
Well they did bet on the Dreamliner, fell on their nose and still recovered.

I mean realistically in this particular category (narrow-bodies) they've essentially been playing catchup for the last _40 years_; ever since it was released they've really had trouble competing with the A320. Their inability to do basically anything right feels newer, but the 737 has long been a weak spot.
Only if a company is completely blind to buy Boeing planes in 2025! It does not matter if the places are millions of dollars cheaper, all the money spent with lawsuits and lawyers when things go sideways, plus the airline name dragged to shit, I don't think it is worth.
It's likely this. Airbus has a backlog of ~7500 A32x orders right now, and produces about 75 a month, so if you order one today, you're looking at eight years.
Though also some budget airlines like the 737 because it's _short_; it's not as high off the ground as an A320, making access via airstairs more feasible.

The interesting thing for me about this particular tale is the commercial genesis of Airbus and the incentives of the management team have led it to catch up despite Boeing have a 20-year head start.
When you're not totally absorbed by the share price, and instead you're trying to build a sustainable long-term business that can pay off decades (or generations), later, you get to make decisions that lead to a more sustainable and trusted business.

There's a Chinese saying: "Wealth does not pass three generations". Three generations of Intel CEOs after Grove: Craig Barrett, Paul Otellini and Brian Krzanich (the progenitor of much of the mess that Intel is in today).

Surely, Google here is the cautionary tale? Though I guess it started with the cloud for them.

But Boeing introduced several new planes during these 20 years. If anything, they abandoned the idea of a new design and introduced 737 MAX as a response to the competition - A320neo.
