It’s not as good as Google from 20 years ago, but much better than Google today.

I didn’t choose it for the privacy, I chose it because I wanted to actually get results for my searches.

Google gets me answers about 20% of the time,
Kagi about 50%,
and (generic - not Kagi) AI about 80% of the time.

The problem with AI as search is that the other 20% is when it will confidently give me wrong answers and waste hours of my time, so I guess Kagi is still useful to me.

Magnifying glass + lots of typing ones and zeros.

Multiple independent braking systems and adequate maintenance.

A single failure may cause the escalator to stop working, but it takes 3 failures in a row to make it catastrophic. Regular maintenance catches this failures before 3 in a row can occur.

If any of the stairs are damaged and cannot stay attached correctly, there is a chance of falling into the machinery below, which will not stop just because a human is in the way.

If the failure is in the braking system, it can quickly turn into rapidly moving stairs, which can be very lethal.
Most escalators have multiple independent braking systems so that this doesn’t happen, but some poorly maintained escalators have been discovered with 2 or even all 3 systems disabled.
