IMO, no, cruise ships have NOT suddenly become dangerous. As with life, there is a risk in anything with we do. Communication is different today than in the past, so we are getting information quicker and more broadly. Add in our natural sensitivity to cruise line issues right now and I can understand your question. I would also put forth that the cruise line response to the event is crucial. Ask the RC cruisers how they felt about the incident and compare that to the feedback from the other cruise line recently in the news and I am sure that you will see a completly different outcome.
If anything, I would submit that cruising is actually safer. Technology allows quicker identification of storms, faster identification of ships in the area and even at greater distances in years past, etc.
I have been on 10 cruises, with #11 coming up and fully intend to continue cruising as much as possible.
