this should end well

or a whole new technology invented other than radio waves for data transmission

are any satellites using laser downlink yet or is line-of-sight too temperamental with weather and planes?

Let’s launch hard drives back and forth between earth and LEO. Like sneakernet in space.

Laser links for satellites work fine, but if you're up against a 10 year old spy satellite or you're selectively jamming their SAR (radar imaging) or GLONASS positioning rather than their comms...

I mean isn't space X testing satellites with sat to sat lasers?

In that case you don't need to ground lasers, you just beam the data where you have unjammed communications with the cost of higher latency.
