Interesting. I have had bad cell connectivity in unfamiliar airports, though, where I could barely keep a connection to e.g. the Lyft servers. What if I can’t download the module when I need it? I don’t think requiring the user to download it in advance of their flight is viable, either. If we lived in a world of universal, homogeneous, inexpensive connectivity, I’d be satisfied with the solution you mention. I guess if they had location/policy micro-modules small enough to fit in a single MTU, then anybody who could connect to Uber at all could be served.

It still boggles my mind that there could be ~100M meaningful instructions in a program.

Which sucks. I arrive in a new country, and need to find internet access???

Mate.. how are you going to get your uber anyway without internet?

If you want to use Uber afterwards... yes, you already established you'll rely on internet access.

How are you ordering an Uber without internet access?
