Does Technology Make Us Feel Safer (Even When We’re Not)?

Do you think Titanic's passengers may have believed that having wireless communication, aboard ship, helped to make them safer?  If that is what the passengers believed, do you think they were right? Why, or why not?

If Marconi's wireless message was able to travel 1700 miles (from Cornwall to Newfoundland), in 1901, why was Titanic's wireless transmission-reception capability limited to 500 miles (in 1912)?

How are today's mobile devices, which are also "wireless," similar (or dissimilar) to the Marconi wireless aboard Titanic?
