        Guys, anything that fits in a tweet is very unlikely to be a "best thoughtful argument." Link me to longer careful discussions, instead of trying to summarize some argument in a tweet.

        In ecology, invasive species are considered problematic not so much because of direct harm they do (there may be none) but because they have potential to irreversibly change the ecosystem. Something similar can be said about mass immigration from incompatible cultures.

        In other words, irreversible change to complex systems should be considered bad by default until very good information about its downstream consequences is available.

        But irreversibility works both ways. The immigrant waves are not going to be around forever. Mexican migration has plummeted from its peak. We have maybe a few decades left before GDP convergence makes East Asia do the same. A few more till South Asia slows to a trickle.

        We have a limited window of opportunity to get people from around the world on our team. Closing the border to them in that window is also irreversible.

        Why is getting people from around the world on "our team" a good thing? What does our team stand for?

        @TheAmericanLib2 isn't saying good or bad. Saying that the current complex system includes (and always has) waves of immigrants. Changing that could be considered the type of activity that should have the downstream thoroughly examined before engaging in it.

        Nonsense reasoning. Massive changes cannot be considered a part of a system because they are unpredictable. Systems by definition are predictable. IOW, you attempt to escape my argument by redefining “system” as lack of one.

        Quoting your own tweets to ensure we're working off the same raw material... "systems by definition are predictable".. "changes cannot be considered part of a system because they are unpredictable". That is an important part of the argument and you stand by it.

        Hive mind by @GarettJones is not against immigration but it does put a fairly strict requirement on who a society should allow move

        Hive Mind is basically a straussian argument for a conservative immigration policy.
