Had a conversation this weekend with 17yo son about how one day his morals will be tested, peer pressured. He'll be asked to just look away. It may be a friend he trusts. What you do when your morals are tested is who you are. Have the conversation with your sons. It's the least each of us can do.

In Estonia, there has been a similar argument made that internet voting favours certain parties. However, it has been done for long enough for these parties to fall out of favour as others started winning. The solution for the critics has been simple: now these other parties are rigging elections. 🤷‍♂️

How can Europe survive the AI tsunami?
Artificial intelligence is making its way into every corner of our society. That is why it is crucial to have a clear strategy for the use of AI and for the values that should guide its actions. At the Digital Tech Summit, Estonian experts contributed to the debate and emphasised that we, as individuals, also bear responsibility – and that with a few simple steps, we can maintain control over the technology ourselves.
