while some people will stop buying desktops and laptops, claiming that anyone who only produces desktops and laptops will go bankrupt is rather far-fetched.
That's like saying that since since many people have already stopped buying desktops and instead buy laptops that anyone who doesn't have a laptop presence, and all the companies who only make devices and cards that work on desktops are going to go bankrupt. that's far from true, they can continue to make a nice profit selling there devices.
IBM only makes mainframes and servers, the vast majority of people don't buy such systems, and haven't for MANY years. why didn't they go bankrupt decades ago?
