I'm pretty sure that Threadripper and ARM based servers are not used for the same type of tasks.
Also most of these micro form factor computers are based on mobile hardware CPU's GPU's and priced higher than a laptop with simillar specs. there has been a micro gaming pc space in the market for quite a while, it's not new just expensive so not as popular, there are changes coming but I super doubt it will be night to day like is describing. and far from over night.
