that’s only true if you’re a trump supporter, it’s absolutely true if you’re not. There are most definitely concerns to be had, as there always are, but globalism is fundamentally good for the economy. There is no world in which this isn’t true, so you should push towards globalism, even if there is some risk, because it will likely stabilize relations significantly.
there are two big arguments for a denser layout, notably you move your hands less, which means you can type faster, statistically speaking. It makes it easier. Generally you see typing speed track roughly with this over time.
And since you move your hands less, it’s ergonomically better for typing, so you get less strain, you have better ergonomics in general, you can type longer, and even faster since there is less strain.
Different layouts optimize for different things, some optimize for efficient roll combinations, some optimize for switching between hands as optimally as possible. Some don’t really do any of that (qwerty) which also have a significant impact on typing.
