alt Hacker News> the fact that pieces from the 70s snap perfectly into ones made today is mind blowing
Is it? It's not like it's hard to keep producing the pieces to the same original specifications. If they snapped then they snap now.

How many plastic things from the 70s still work perfectly with no cracking or warping?

It’s extremely hard to build consistent products to the spec.
There are a lot of knock-off LEGO on the market now. We get them as gifts. Some of them stack okay, some are too tight, some are too loose.
It’s hard to manufacture at scale at these tolerances and keep it that way for decades.
Did you even read the article? No, even just the Title? Nothing is ever impressive I guess. Certainly not a 60 years running manufacturing process where your childhood pieces can be passed down and combined seamlessly with a set you just bought for your kid. So trivial and easy to do guys.
I think it's more the consistency of product design than the manufacturing process. Everything around me, especially in the software world, seems to change for no good reason on a frequent basis. Companies change products all the time for reasons other than utility/functionality. A consistent specification over 50+ years is an outlier.
