It's anyone's guess how long it will take for demand for pilots to pick up again. There are way too many variables which just cannot be quantified. Any forecast at this stage is merely an educated guess based on data which may or may not be close to how things will actually play out.
When will borders reopen? When will economic activity pick up again and with what amount of damage? How long will it take to get close to the pre-COVID levels of GDP, unemployment, company revenue and individual disposable income? When will individuals be willing to travel again and when will the majority be able to afford it? Which airlines will make it and what will they look like in terms of fleet numbers, route networks and pricing? And a huge number of other questions which simply cannot be answered at this stage. That's what will determine the future of the pilot market in the years to come.
Unfortunately, right now it may appear as the end of the world. And, sadly, terms like "carnage" and "bloodbath" would not be inappropriate to describe the present state of affairs. The good news is that, with 99,99% confidence we can assume that it's not going to last forever. And not even for a decade. Solutions will be found to get the world moving again, to get people working, earning and spending. But the exact timeline of recovery depends on all those things which we don't know yet. So, for now, patience is king. Make sure you find a way to provide for yourself and your loved ones, keep an eye on the situation as many things can change quicker than we expect and, if you are certain that you want it badly enough - one day your turn to take the hot seat will come. It might not be as soon as you would like, but it will.
