1. Yes.
2. and 3. Have you not studied the career that you want to pursue?
Yes, there will be hiring in the future. But not right now. This entire industry is cyclical. I was born in 1984 so lets see. 1984-1986 airline strikes, Eastern out of business, Pan Am out of business, Gulf War, dot com bust, 9/11, more wars, MERs, Age 65, 2008-2010 financial crisis, bunch of airlines disappearing in 2008, airline mergers, SARs in there too, another merger (2 for me already, 2 binding arbitration SLIs), and now Coronavirus.
The good news this time around is that the airlines are as financially strong as could be going forward and lots of retirements. Given where you are in your career, don't even sweat it. Study the history of airlines and this industry. And get used to it. This virus crisis will pass at some point, and then later we will have some other crisis. You did come off a little tone deaf. There is no promise for you to be an airline pilot. And while things were great for hiring and "relatively quick" from 2014-2019, there is no guarantee of a "relatively quick path" to being a major airline pilot. You are and will always be at the mercy of the industry and things beyond your control. Seriously: if this concerns you, then you haven't studied your career choice history very much.
