1929 Global Depression. Will History repeat itself?

I watched the documentary of the Global depression that happened in 1929, have felt the sadness even seeing on the video and realized that we should all learn something from it. It is scary to think that the price is near the long term trend line or resistance from 1929.

In the Elliot wave theory, I followed the sequence of past recessions. I am not sure but my count is it might happen in 2020 or 2021. I really hope not.
I just want to be aware of it and not negative. Things do happen for a reason and we can still look at it in a different and positive way Just be ready for it. Maybe upskill or strengthen the relationship with loves one or think of what's more important in life and how to surpass difficulties if ever it happens.
