I don't know the details but both use services from the carrier. I think google hosts for the carriers but there are checks thats rely on the carrier. If you look at the details for google messages it address specific URLs based on the carrier.

For iPhone its all carrier depend. If the carrier doesn't support it, iPhone will not have it.

Localsend is a good one to try out. Works with all devices and is pretty fast. It does however require an app to run.

For something you can run off the web on PC you can try pairdrop. This doesn't require an app to work on PC. Haven't tried it without the app on mobile so not sure if it will work on there via web.

I prefer Localsend over pairdrop due to local send being completely server less and all local.

I would avoid anything built into the TV.

1. Its starting to be used for spying on you
2. The chip they come with are usually not that good unless it's a high end TV.
3. They are building ads right into the TV themselves.

I would not connect the TV to the internet and use a external media player. Either a Nvidia shield or an Apple TV is your best bet.

You can also try building a media player yourself using a small computer.

Note - The self made media player will be more limited in terms of apps available, unfortunately, as well as streaming quality from some of the streaming services.

Its due to compression of the video in order to fit on a MMS message, which is very small. Android uses RCS as a new message standard that can send bigger files but Apple has yet to add it to their OS. Its similar to how Apple uses iMessage to do the same, however this is not a standard and is locked to only apple devices.

Apple is supposedly adding support for RCS during the new iOS update but until then you can use a different messaging app to send better/larger files.

I recommend Signal as it is easy to sign up and start using while also being private.

Signal is probably the simplest to get started with.

There is also element/matrix for more of a discord type feel.

SimpleX if you want something more anonymous.

Isn't matrix more like slack that you are looking for?

Check out LocalSend. App that let you send things over local WiFi. No server required.

Mostly their marketing practices. They are designed well but mostly designed to keep you locked in one way or another.

For me, their desktop is not as intuitive as people make it seem and lacks simple shortcuts that most other desktops have.

On mobile, its the restriction of customization and options. They are getting better at customizing but still limit you on options for anything outside of their apps. They claim to be private but follow similar practices as other companies, just in a more quite way with better PR.

Ignore or if you must reach out some way, then through the work email keeping it professional.

AI doesn't automatically equal not private. Its probably still has private as it was before.

Now if it starts showing it knows things about you, then I'll be concerned.

By A.I. are you mostly talking about the chat bot kind like ChatGPT? Because A.I. is a pretty vast field with many benefits.
