I think both are true depending on the software. But yes it's unfortunately too easy to run into bugs daily even if one does not use new apps every day. The reason for unreliability is probably the same reason why things are slow: developers and project managers who don't care about the users and/or who are not incentivized to improve performance and reliability. If you think that "not caring about the users" is too harsh, consider that users do suffer from e.g. unoptimized web pages or apps that use mobile data in obscene quantities. This has a direct consequence on people's wallets or loss of connectivity which is a huge pain. As developers we can all try to instill "caring about the users" into our team's priorities.
