Remember when you first started cruising decades ago? With a limited budget, your cabin was small and the only view you had was during daytime through that small, round porthole. All you could see was the sea. If you were in an inside cabin, you saw nothing.

Now, with ever-advancing technology, even the lowest inside cabins on cruise ships could offer more enjoyable porthole views. Of course, the scenes are digital, and portray fascinating video of soaring clouds, high mountains, stately sailing ships and sandy beaches.

Now on some, there are animated cartoon and movie characters. Passengers on Disney’s Dream and Fantasy ships will now enjoy inside what they fantasize about picturesque happenings outside.

PJs for those weary travelers who book long overseas flights with Los Angeles as one of the destinations. The airline offers a full set of pajamas for its Delta One business class passengers to wear while snoozing on their flat-bed seats. The PJ flights from LAX are to SYD and PVG (Sydney and Shanghai).

In-flight entertainment is advancing rapidly. From squinty tiny TV screens 10 rows in front of you to individual seat-back displays of everything from old sitcoms to new movies to breaking news.

Now, according to scientific predictions, virtual reality head-worn devices are soon to become a ... well ... reality. You’ll be able to strap on a magic helmet that takes you away from your cramped airline seat to a Hawaiian beach, Medieval battle game or front-row seat of a Broadway show. And, in the future, even that will be surpassed by making the experience a full three-dimensional immersion, where you’ll be IN the Broadway show.

Consider what the imaginative senior will be able to do, in flight and at home. Dance with Fred Astaire, romance Marilyn, rock with Elvis, run the bases with Jackie Robinson and storm San Juan Hill with Teddy Roosevelt. For the more patriotic, join the wigged guys and sign the Declaration of Independence on a hot July day in Philly.

For people who need instant rides, first there were stage coaches, then horse and buggies, then taxis, followed by Uber. Now there are plans for cars that can take you places in the city without a guy in the front seat.

Google calls them autonomous vehicles, and after a million miles of testing, the next step is to practice pick-up service. According to reports, as early as a year from now, the first ones will be tried in non-busy traffic areas, such as office parks and limited access campuses.

If you think taxi driver Travis Bickle was crazy before, consider how homicidal he’ll be when he sees an autonomous Google take a customer away from him.
