Based on my Rene Auberjonois post in CS, I think I could predict some celeb deaths by mentioning how they are the sole surviving major cast member of certain films.
People will be born and will die.
Political stuff will happen.
Terrible disasters will befall.
Scandals will make headlines.
Stuff will fall from the sky.
Sea levels will continue rising.
Bullshit will be promulgated.
Tweetstorms will erupt.
Volcanoes will erupt.
Pimples will erupt.
Protesters will disrupt.
Firms will go bankrupt.
Preachers will interrupt.
Waterfowl will migrate.
Ocean pollution will spread.
Incels will masturbate.
Squirrels will chase.
Luna will explode.
I’ll avoid surgery.
I forget the rest.
2020 will be the year of the Great American Snappage.
Twitter will be used to lure hundreds of people to a phony event for purposes of a mass murder.
CNN, MSNBC and possibly the broadcast networks will stop covering Trump rallies at some point. Many TV campaign ads will be refused airtime.
One or more of Warren, Sanders, Pelosi and Trump will be physically attacked and possibly killed.
If Biden is the Dem nominee, enough snowflakes in places where it matters will refuse to vote for him, throwing the election to Trump, assuming it takes place and he does not disrobe during one of the debates. Civil disturbances will be instigated in swing states and the National Guard will be deployed there and used for voter suppression.
Following the election, a consortium of billionaires using a straw corp. will buy Twitter and shut it down.
ABBA will reunite. (yeah there’s hope, there have been rumors of new recorded songs for some time now, and maybe by releasing them they are pushed to make a stage comeback. One can hope ;))
A tornado will strike the heart of a major Midwestern city. Loss of life will be relatively small but property damage will reach the tens of millions.
One of the major lottery games will reach a jackpot of one billion dollars. More than a dozen different people will choose the winning numbers and split the payout.
Google will be bought by a nice consortium of companies with vague names, all of which are owned by the Chinese government.
It will be the end of free speech on the web.
(on edit: oops, the OP asks for predictions that will happen during the year 2020. My prediction is about the decade of the 20’s.)
After a third inconclusive round of elections, Israeli Prime Minister Netanyahu will resign his position and retire from political life in return for a full pardon.
We are far closer to the opposite situation due to a liquidity trap. Much more similar to what happened in Japan for the (poorly named) “lost decade” there. (More like 20+ years.) There interest rates actually went negative near the end. 6% inflation would have been better for them than what happened.
