So a local recession is likely already happening. The question is whether or not this spreads to be a full US-scale recession.
I do believe that the technology sector is in the end-stages of a bubble, but whether or not that causes a drop in GDP is another question. The WeWork IPO-failure, as well as Peloton IPO drop, has shown that "tech" companies are not as valuable as VCs thought they were. (WeWork isn't $40 Billion as Softbank expected but is instead ~$10 Billion).
So now what? Well remember: 2008 was a "Great Recession", and 2001 was a recession but mainly isolated to the tech-sector. A recession like `91 (~8% unemployment) is probably what people should be thinking about from history.
There's probably no chance of another 2008-like "Great Recession". But the US economic cycle cannot boom forever, and we've been booming for nearly 11 years now. Some kind of recession is inevitable.
