They release the submunitions at much higher altitudes than they were intended so they spread across a much larger area and thus ineffective at hitting anything other than an urban target.
But on the plus side for the Iranians they separate outside of the interception envelope of even the exo atmospheric interceptors Israel has so they actually get through even if each sub munition is only a nuance at best.
This is how one way fiber optic connections for air gapped systems work.
You can have a stealth drone which is effectively invisible to SIGINT transmitting real time intelligence to a satellite whilst either operating autonomously or receiving commands via a wide area encrypted broadcast (yes I know you can theoretically detect receivers through signal attenuation but at these distances it’s effectively impossible to do).
The reason no one is building large FPGAs is that there is no market for them.
If an H200 scale FPGA was viable we would have one.
It’s also not that different than how TPUs work where they have special registers in their PEs for weights.
FPGAs don’t scale if they did all GPUs would’ve been replaced by FPGAs for graphics a long time ago.
You use an FPGA when spinning a custom ASIC doesn’t makes financial sense and generic processor such as a CPU or GPU is overkill.
Arguably the middle ground here are TPUs, just taking the most efficient parts of a “GPU” when it comes to these workloads but still relying on memory access in every step of the computation.
For email each individual message should be encrypted if you want any confidentiality and even then the meta data is in the clear.
And this is because in order to send or receive an email the provider needs to access it. If they put it into a box later on to which they do not hold the key that is just security theater at that point.
With MSFT cloud backup of keys is an opt-in. With Apple it’s an opt-out.
You also do not have to backup keys in the cloud, however for most users it’s the best solution since for them data recovery in case of a hardware failure is more important than resiliency against state level adversaries.
Many of these securities do not have a secondary market that isn’t in the US. Push comes to shove the US can block a lot of these trades.
$8 trillion is about half the M3 of the Euro.
In fact there are only about 20 trillion dollars right now, there isn’t even enough liquidity to cash out.
New discoveries don’t happen in a vacuum.
