Péter Szilágyi, a member of the Ethereum Foundation and head of Geth development, expressed deep doubts about the crypto industry on social media, "I often wonder if I have chosen the wrong industry." He compared the crypto industry to a casino and believed that its contribution to mankind was minimal. He pointed out that although it takes time to build a new monetary system, the industry should create some truly useful products in the process, rather than simply pursuing value extraction. Szilágyi questioned why the current crypto system will not collapse, believing that the industry has only achieved a huge value transfer so far, but has failed to create any real value. He emphasized that relying on luck to achieve success and transfer funds to non-crypto projects cannot be regarded as a success in the crypto industry, but only a diversification of wealth for individual lucky people. He believes that the industry has reached a point where it must create truly useful products, otherwise it should consider exiting the market. Although Bitcoin attempts to become a safe-haven asset, other projects are seen as merchants selling shovels in the absence of actual gold mines.
