I doubt Escobar would use Bitcoins to store funds. They are traceable and are too volatile to store illicit gains. But to carry transaction he would use them on massive scale surely. Cash is sort of the opposite. Not very convenient to carry big illicit transactions but as a store of value it is a way better thing.

GC in Java is the best in world with a lot options and knobs that allows to tune to particular application requirements. Still some trading platforms using it disable GC and just ensure enough memory is available so memory leaks during the trading hours would not matter before the application will be restarted.

I worked on a project with a network server written in Go with soft realtime requirements. In theory Go should be very good fit for it especially given GC tuning towards low latency, not throughoutput. In practice the latency spikes from GC were bad and there were no good options to resolve those given the deployment constrains and the amount of third-party libraries used.

Weak measurement experiments have shown that one can observe the whole path of a particle in a double-slit experiment and there is nothing wave-like in the results.

The experiment does not demonstrate wave-like properties. It can be interpreted that way, but purely from experimental properties one can also interpret the result that photon traveled by curved path which brings path-integral formulation of quantum mechanics when there is nothing wave-like but there are just probabilities of a particular path.

There is no interference pattern from a single photon as it hits the registration device at a particular place. But collect a big enough sequence of single photon measurements and it emerges.

This is the reason for statistical interpretation of QM that states that a wave function is just a way to calculate probability with no inherent meaning.

So wave-particle duality is just an artifact of Copenhagen interpretation of QM, not something that one can observe. What one clearly observes that photons travel through a region where they should not classically be and never appear in the region where they should be classically.

Note that even classically waves does not exist as they are just an artifact of motion of collection of molecules that on average can be described by wave-like equations.

Germany has not learned anything from the war in Ukraine and still think that dependence on gas imports from other countries is fine even for backup.

The main advantage of gas plants is that they support variability. In a world with enough battery storage to last for days that would be irrelevant. And as an insurance against rare events it is better to keep coal plants as transportation and storage of coal is vastly more resilient to interruptions.

Keeping coal plants around is cheap to cover that. Longer term things like producing ammonia during summer and converting it to electricity in fuel cells will allow to remove needs for fossil fuels completely.

Just by scaling up the existing technologies the full cost including installation and maintenance of a grid-scale battery in 5 years will be below 100 usd/kwh. So the price is max 400 billions or 1% of US GDP.

Batteries already kill peaker plants as a grid-scale battery that lasts 4 hours became cheaper than running natural gas turbine to cover the evening demand peak.

And vise versa, a proof that P!=NP do not exclude an algorithm that is fast enough for practical n.

Particles do exist for practical purposes. If one can distinguish individual photons, then the picture is nothing but a bunch of particles with only averages producing wave-like pictures. But the puzzle is that they do not travel in straight lines and we cannot predict individual point where they will hit.

I have used gandi.net for many years. They provided good support and offered things like free email forwarding. Then they were bought and the new owners just double or more prices and made anything extra including email a ridiculously expensive extra.
