The lesson is clear. You cannot delegate your defense to others if they are in competition with you. I don't understand why my comment got so many downvotes. I would have appreciated a discussion on the topic instead.
The real estate sales guy is also trying to sell the idea that Europe has no own defense, which is simply untrue.
Europe (excluding Russia) has the second most powerful military in the world on most accounts, with proper technological replacements for everything sold by the Nato ally on the other side of the Atlantic. (Much thanks to Charles De Gaulle who knew the Americans could not be trusted).
But a war with the Moscow State going on in Europe is a big thing. Which of course makes Europe weak in the west, and can be taken advantage of.
I think the lesson learned here is that Europe (and Canada) needs to close ranks and unite. Which may not be a preferable outcome for USA. And before T with a functioning Nato command, there were simply no reason to do that.
Re Greenland, we were in cooperation with the US for decades and the US has had its largest overseas base in Greenland in a friendly way for the free world to protect against the Russian and similar dictators. I'm not quite sure of the lesson there. Do not cooperate with friends of many decades because they may turn on you one day?
Maybe these papers:
"Attention Is All You Need" (Transformer paper, 2017)
"Improving Language Understanding by Generative Pre-training" (GPT-1, 2018)
"Language Models are Unsupervised Multitask Learners" (GPT-2, 2019)
Even Litecoin officially supports privacy these days via Mimblewimble / MWEB, although the privacy is not as strong as Monero. Litecoin is easier to work with since all crypto exchanges support it unlike with Monero. I would like to see Bitcoin similarly support Mimblewimble / MWEB.
Bitcoin Lightning also has privacy, although it's not as strong as MWEB and obviously nowhere near Monero.
It’s likely an attempt to steal usernames and passwords for privilege escalation. I had a large corporate client who faced a very similar issue. In their case, the scammer not only registered similar domains but also created Google Ads campaigns targeting those domains. It’s worth investigating further and taking preventative measures to protect your brand and users.
Is the brick more important than the building? each level of abstraction has its use case and its advantages (and disadvantages). Better not to criticize the level of abstraction but to try to improve it. Even from the bottom with better bricks if possible.
