I'm inclined to agree, but we're starting to hit the zone where I feel I'm using a tool of questionable qualities because of lock-in and the absence of sane competitors. The Unreal Engine IDE runs at 10 fps on my current-gen iMac, an expensive machine based on 2010's hardware and no upgradeable parts that takes minutes to boot up into an increasingly DRM-plagued OS where all the innovation goes into iOS-like features I don't use.

I disagree vehemently that this is what's going on. If that was the "problem", my (software) complaints would not exist.

I imagine like Iron Man where he can divert resources to his weapons from his thrusters and stuff. They do keep adding things that need to run when I wish I could selectively turn some things off.
