I don’t even know where to start in showing how ridiculous your logic is, so I’ll simply comment on your statements.
1. Apple moved to the industry-standard modern USB ports (all old USB ports have been officially discontinued by USB consortium). This gives the MBP the most flexible array of ports, as each port can be used for charging, video, high-speed connectivity, as a normal USB port etc. etc.
2. Apple discontinued 32bit software because nowadays there is no sense whatsoever in writing 32bit software. It’s 2019. Fix your broken code already.
3. Apple has made it simpler for iPad developers to port their software for Mac. The goal is to bring more interesting software to the Mac side, not to dissolve the Mac. App developers make most money with iOS, not many bother to develop for Mac - Catalyst aims to change it.
Finally, people have been claiming this thing since 2010. Ten years later - and there is still no OS fusion happening.

It’s just a theory, but I think Apple is moving all of their OS’s to a common goal; appleOS. This new OS will be a single operating system that is modular in design - meaning you can add or remove “modules” depending on which devices will run the appleOS.
Hate to be the one bringing bad news but that’s how it worked from the start. All Apple OSes are forks of each other. They use the same system code and same basic libraries (it’s open source, check it out). The differences between the individual OS versions are device drivers, basic configuration as well as shipped libraries and apps.
Simplifying it a bit, one could compare Apple OSes to different Linux distributions.
