In the context of running a business, this is known as build vs buy. At the end of the day, there's a core part of your business that only you do the best in the world. It's important that you and your engineering team focus on that core and let other 3rd parties handle the non-core parts. It'll be cheaper and they will do it better (it's their core).

I am old-school and I've learned from micro electronics to computer languages, ofc not to the extend of an academic education but good enough that I only need real specialists to help me.

but I think Roger Jin made a good point. I also know some counter arguments about blackboxing and how often externalities backfired ....

I will just say it depends on what your focus is and what you want to achieve. And even than you would've to really audit your payments / resources.

So you can actually create "real world" scenarios and make real assumptions / assertions about it.

I'm curios what the common denominator will be :)
