"IDC reckons the market will hit 55.2 million by 2023"
Did they factor in the fact that current hardware is used for much longer these days ? My current rig was last updated in 2015, and I have no urge or need to update it now. Laptops are a different story, they cannot be upgraded in any meaningful way aside, perhaps, memory, but they can last a good many years as well, especially the more powerful ones.
I doubt that a change in chip availability has that much of an impact.
