Yes. But we should not forget that it's unrealistic for Macao, a mature economy entity, to totally remove its pillar industry - tourism or gambling, to financial service industries or high tech industries, i believe new-planed city or region like Shenzhen Qianhai or Zhuhai Hengqin, could do it, but not Macao. Macao is indeed a financial center, but it's less developed, it doesn't have a central bank, no future market, it's not even a complete regional financial center. Macao's financial industry depends on HK and China. You must know that as a service industry, finance is to serve the real economy, and its development is limited by the size of its real economy. Macao's economy base is too small to attract large amounts of investment, no money flow through, no finance to do.
Maybe it's good to develop high tech industries as you mentioned. But it's still difficult to start a thorough transformation from gambling to high tech. You gotta have research centers, specialists....
