Not every person, but many could encounter this while upgrading to Catalina.
I can not see anything abnormal here.
It looks like nydailynews website is a resource hog. Just for curiosity opened on my laptop and it immediately used 90% of CPU power and stabilized at 28%. Anything above 10% usage of CPU will lead to warm/hot laptop experience on any laptop.
So nothing should ever be over 10% usage of CPU, and if it is, the computer will likely get warm? Interesting. I'll look into that on both this new pro and my old 2013 air.
