The second example in the reading points out that pirates are not interested in crewless ships, however in the lecture the man points out that today's hackers can control the system of the ship and to direct it to a different place from the original.

The last example that we can read in the text points the small risk of accidents in crewless ships compares to the crewed ones. On contrary, the lecture points out that the most of ships today are controlled by human so it's turn more unlikely an automatic system take good choices in situations that only human can anticipate e fix.
