I literally (as in 30 minutes ago) just fixed a bug in 10 minutes that I thought was going to take me 3 days to fix using https://pernos.co/ (a "timeless" debugging tool that wraps Mozilla's `rr`). This is a factor of speedup on the order of 100x+, not 10x.
I highly recommend checking this tool out if you value your time.
