I think we are experiencing extreme inflation, just not in CPI goods, but rather capital assets. Stocks, bonds, real-estate, all are completely disconnected from any reality right now... traditional valuation is irrelevant and we are now trading purely on sentiment, ala meme-stonks.
Just look at the IPO landscape, and the ridiculous market caps of companies who not only have never had positive net income, but in fact have an increasing loss every year! They can continue doing this because the capital markets basically throw free money at them, it's easy to raise debt at low rates and issue additional shares if needed.
As they say "don't fight the fed", and timing the market is impossible, but I can't even begin to fathom the blood-bath that will ensue if rates were increased to a reasonable level.
