The problem with the question of why is that you can always ask why again. Say we do understand the mechanism of the big bang. You can still ask “why” about why things are that way. Which is why in my view that’s still more of a “how?” “Why” is more of a question for philosophers than scientists imo.
shrug I guess we’ll see but I don’t think it’s at all far fetched to think that more people will be lining up and saving for a switch 2 compared to a new xbox, even a year after the launch. The switch is one of the most successful consoles of all time and I don’t see any indication that demand for the switch 2 will be softer.
