I suspect many villagers in Tai O would be utterly horrified at the idea of bringing the cable car directly to them. I know people who chose to live there BECAUSE it is remote. Not everyone wants a direct MTR to Central. And as stated by someone else, a more frequent ferry service would probably be just as good, if not better. The cable car to Nong Ping currently takes about half an hour (excluding the queuing time, which can be much longer than that) so an extension would be even longer. The bus from Tung Chung to Tai O is only about 40 minutes. They wouldn't gain much. The ferry from Tai O to Tung Chung is about 25-30 mins, so that's an improvement, and then to Tuen Mun another 30 mins - which gives them more options about where to go. But it does not run very often, so having an (hourly, perhaps) ferry would be a very cheap yet effective solution. Remember, there are not that many people living in Tai O - they don't actually need infrastructure catering for 100's of thousands, just enough for a few hundred.
