Eh? It's absolutely an option, from a technical weather forecasting perspective, to see that a storm exists, and to abort a particular plane flight before it takes off, or reroute to another airport. This happens all the time in extreme weather conditions (eg winter anywhere it snowstorms). That airlines choose not to more proactively cancel flights in moderately inclement weather is a business decision, not a shortcoming of our weather forecasting abilities. Flights often get delayed by weather at the other end - it's jarring to hear the pilot say the flight you're on is delayed due to heavy rain at your destination, when it's a gorgeous sunny day in your current location, but it happens quite frequently!

The comment you're responding to is talking about general aviation, small propeller planes. Those have a relatively high incident count for flying into bad weather. When the pilot is only trained to fly visually (VFR) and enters low visibility or clouds they're very likely to crash.

This isn't a problem in airline flights. There are very specific rules about when you can and cannot depart and when an alternate airport and fuel for it is required. No airline takes off without satisfying all the rules and almost no airline cancels a flight for weather while the rules say it could go.

General Aviation is a category that covers a circumstance of flying rather than of aircraft. I think if you've got the necessary time and money to buy your own personal jetliner, insure it, get all the paperwork signed off for it and for you to fly it as a hobby, that's still GA, although where somebody with that much time on their hands gets that kind of money escapes me.

Some mere millionaires own jets with decent performance, aircraft that in capable hands could fly well in most weather but they're still GA and too many of them still die in bad weather.
