What's the alternative to the us and silicon Valley? Companies were trying to make Austin happen and that was a failure. Now one talks about that anymore.
Within the US, I would say New York, but the taxes are of course no better there than California. Both FL and TX are still growing fast in population (not sure about Austin or tech specifically though) while CA is experiencing net outflows.
Outside of the US, London (+5.4% annual growth in 2026) is probably the biggest concentration, with high quality inexpensive talent available from universities both within London (ICL, UCL, King's etc.) and from the nearby Oxford and Cambridge universities. Much of that talent used to flow to the US, but given the current administration and restrictions on H-1B, may now be more likely to stay in the UK.
Singapore (+26.7%) is growing very fast and is now in the top 10.
