From long experience, I would say contemporary (rather than modern) opera is anything written in the last 40-50 years. The age of the genre is now well over 400 years, so we need to take some perspective.
I have good news, the art form is alive and well.
During the last decades we have had also the full recovery of a big part of opera heritage, the Baroque period. That was mostly lost, except for a handful of pieces, that were not even correctly performed in many cases.
Even within the Mozart-Puccini historical period that many fans and general managers adore, there have been quite a few neglected operas that were given a new opportunity.
Today there are many new operas, but then again there were many more new operas were written in the past. Just one example, in the early 19th century there were
hundreds of new operas each year. How many of those operas written in, let's say, 1831, are performed today?.
In 2022, and still officially recovering for COVID in some countries, according to Operabase there were 15,000 performances of different operas, in different places (the actual number of performances was much bigger, as they are counting Turandot at Teatro Real, for instance, as 1, while there are several performances offered during one month)
So you see, Opera is not going to disappear tomorrow. More probably, our grandchildren will still continue to discuss about that, fifty years from now.
