I don't think it's time, it's priorities; your work is, naturally, a lower priority (both in terms of your focus and your actual time) than your kids, spouse (if any) and yourself. Whereas in the Before Times, it was just you and your keyboard.
Having family as priority compared to work is more than fine, it makes you (potentially, not necessarily) a good human being, a good parent or husband. This world needs that 10'000x more than another code ninja optimizing some corporation by nanofraction of a percentile.
The opposite is extremely valid too (to not leave any room for misunderstanding - folks prioritizing work over their kids are shitbags, no exception, and every single one I've met in their later years deeply regret that... apart from outright sociopaths and similar careless crowd).
Focus on career if thats your calling and spent whole live in it if you want, but then please don't have kids. Every kid with missing/bad father figure I've ever met later in their lives was a mess in one of myriad ways, endlessly compensating for this and never actually coming over it, permanently. If you know what to look for, you can start seeing it around you quite easily. It breaks my heart a little every time I see it. These folks often repeat same mistakes of their parents too.
