Many of the people in tech I meet, knew about Bitcoin very early. They even saw the potential. Some acted on that (with hindsight this may seem the "smart" move, but really, it was a gamble with lot of downside potential. Still is). Most did not -which actually, financially or investment-wise, was probably the smart move-.
Those people now must find ways to deal with this internally. The simple thing is to keep convincing yourself that web3, crypto, etc is bad - a conviction that isn't too hard to base in fact, really.
I gave talks in Bitcoin on tech meetups back in 2012. I've had numerous people from back then, tell me that they are really bummed that they didn't really believe me back then, to at least dabble around a bit with some spare change. Or just the tech. I strongly believe there are far more people in the tech scene who aren't this honest, not even to themselves, and instead strongly and loudly "hate" on all crypto.
