My take: If you stay disciplined, you can do stuff which in 2020 you would have never attempted because you thought it would be too complicated. For example -- I am a huge Postgres user and tend to use expensive managed Postgres servers because... postgres admin is complicated. But today, in about 3 hours, I set up a pretty complicated remote follower for a local postgres instance, along with bandwidth limits, all the networking stuff, all running in docker on both ends. Something which would have taken me 3 days of puzzling to get right in 2020.
