I see many posts saying that the stock market is actually at risk because Warren Buffett has been disinvesting from it.
Here's the thing. You're not and never will be Warren Buffett. You're a small investor trying to build some funds for retirement. He's a 90 year old centi-billionaire. He can do whatever he wants with his money. It doesn't mean anything for him. He can afford to go against every single normal piece of advice about investing. If he sells everything and invests into Swiss government bonds with a 0.1% return he'll still be making 2M $ a week. If he invests 5% of his capital in worthless Venezuelan bonds than then collapse and vaporise he'll still be left with more than 90B$. You should be following his advice about building wealth, not looking at what he does with his current money because that's something that doesn't concern you.
