I would definitely trust a doctor making 30 year predictions on a novel coronavirus. They all say they don't know anything about it until it comes to saying stuff that can scare people. Then they are so sure all of a sudden. Lmao.
Here's an analogy.
You have a car. The engine was engineered to run "under normal" circumstances, 500K miles. You then proceed to run the engine to readline repeatedly for the first 10K miles. This causes small but irremediable damage to the pistons & rings, valvetrain, etc. These imperfections can't self-heal because they aren't made to. By 200K miles the engine is ready to konk out after blowing thru a quart of oil every 1000 miles. There has weakening compression in the chambers making it gradually lose power. All this time you're getting warning signals from the central computer that's trying to determine and report deviation from norm.
This is what happens when cells in kidneys, lungs, heart, etc are stressed and die. It creates scar tissue that further stresses the capacity of the organs to function properly. At "10K miles", it's not a huge deal, but as the other "parts" face their normal wear with age; those that were most stressed come upon compounded stress to function properly.
I suppose you could always rebuild the motor, but the body is a bit different and I don't think you would want to be tubed up 24/7 - it's really not that cool to look like the bad guy from Dune but to each his own.
