The point is that we should acknowledged those "cheats" came with their reasons and that they did improve performance etc. But, they also did come with a cost (Meltdown, Spectre anyone?) and fundamentally introduced _complexities_, which at today's level of manufacturing and end of Moore's law may not be the best tradeoffs.

I'm just expressing the general sentiment of distaste for piling stuff upon stuff and holding it with a duct-tape, without ever stepping back and looking at what we have, or at least should have, learnt and where we are today in the technological stack.
