Basically, the answer is "Yes" as long as the routes and operations are reassessed to make them much more usable for commuting. The current routing is distinctly sub-ideal for Central Valley => Bay Area along with San Diego/Irvine => LA If you want commuters to use HSR, you have to make it easy for people to use. This means the line from SF to Sac/Roseville being placed directly along the 80 corridor with frequent stops for locals as well as dedicated express trains. This requires sidings at all tops in both directions to enable passing, something not currently envisioned for 90% of the stops (iirc). The biggest problem with CAHSR imho is that they started grading the RoW and laying track in the central valley before they had started on crossing the Tehachapi mountains. The highest long-term value to HSR is going to be the LA-SF route. The one piece with the longest build and highest cost is the route over the mountains (the existing route owned by the UP and with BNSF having trackage rights is 2/3 single track and completely at capacity, with speeds of less than 30MPH average). There is no way that HSR will be long term viable without that route in place. Until they build that and rationalize the routes, it will be nothing but a faster and vastly more costly replacement for the San Joaquin corridor passenger trains. I want it to be a success. I'm very pessimistic about that in the current state of affairs.
