This word has two connotations, that sometimes overlap. The first is a matter of brute force – accept what I say, and obey my orders. The second is more supportive – you know how I have behaved in the past, and you can trust me to behave in the same way in the future.
In Software, an advanced area, where people are acting sensibly – trust does not even come up. You can use the Internet, because you use established protocols, that everyone has agreed on. It just works, and no trust is required.
This area is advancing rapidly because everyone builds on the work of others – they know how these technical advances work, and they know how to use them. No trust is involved.
This is such an important point, I want to reiterate it – people trust the Computer (and its Software) because they know it works. They may not know how it works – but they know it works.
Compare this to the operation of the Market, that the Economy depends on. It is prone to periodic crashes, because it cannot be trusted. Either due to internal instability (of many kinds) – or to outright fraud. Or combinations of the two.
I refer you to A high-stakes gamble: How Jared Kushner reacted to previous crises. This guy is gambling with other people’s money – and should not be trusted. But he has plenty of support in high places (including President Trump, his father-in-law).
This is corruption – that is all too common in today’s world.
A world that cannot be trusted.
