Do you think we will be capable to leave our solar system one day? Or that getting even to the closest star is impossible.

Yes we will. It's not impossible at all.

Well, getting out is relatively easy. Just get a big enough rocket for your probe. Voyager 1 has for all intents and purposes left the solar system.

However, I assume you mean HUMANS leaving the solar system, which is a hugely more complex task (crew sanity, food, life support, radiation protection, prolonged weightlessness etc).

Nothing is impossible given enough time and budget.

I think we will, we just don't understand space well enough or have the proper measurement devices to do it yet.

My train of thought goes like this: It wasn't until Newton we were able to invent the sextant, which in turned allowed us to traverse the globe. It wasn't until Einstein that we were able to move around in outer space.

I think next level physics and measurements will allow us to move through space more efficiently. Maybe a holographic universe, gravitational astronomy, or mastery of quantum mechanics will lead to avenues that allow mundane interstellar travel

Impossible, no. Time-consuming, definitely. Right now, the fastest speed we think is possible is the Speed of Light, and it would still take ~3 years to get "next door" at that rate. We're not really capable of propelling any considerable mass to the Speed of Light, and we're definitely not capable of stopping if we did. But with technology we currently have, we could get to Proxima Centauri in a few hundred years (maybe not live humans), and that time will only get shorter and shorter. It's just a mater of when we think the travel time is short enough to pay off.

I don't think we'll be capable of making it to Alpha Centauri any time soon. Possibly not at all. Unless we can figure out a warp drive or something, we'd have to be going in generational ships.
That may be possible in a few hundred years (assuming we do) after we've colonized our system, pulled tons and tons of resources out of the asteroid belt and have plenty of manpower and resources to spare.
Assuming that everything goes smoothly, and we're able to settle the solar system, it's definitely possible. If we are able to efficiently mine asteroids and other planets, and build sustainable colonies, we should have abundant resources to make long voyages.
In The Expanse series there is a group of Mormons that pool up resources to take a massive generational ship to some nearby star system. I could see something like that happening, whether it's a religion that finds the will to do it, or a government project, or even just a private project.
So it's definitely possible, it's just that we've got to get well settled in our own solar system first. Really, it's fairly easy to conceive, but we'd have to pass many political, scientific, social and economical road bumps to get to the point of being able to.

Just an interesting consequence of relativity: As you approach the speed of light, time slows down. While the trip might take decades or centuries from our perspective, it can take significantly less from the perspective of the travelers. With an efficient enough vessel, traveling to Alpha Centauri can theoretically be done without generation-ships.

Even without time dilation, Alpha Centauri isn't that far.
If we could accelerate at 1g halfway, then decelerate at 1g the other half, it would only take 6 years without time dilation (3.5 years with dilation).
That kind of acceleration is a tall order though.
At only one tenth of a g, it's still only about 13.6 years to an outside observer.
Google "relativistic star ship calculator". I like the one from convertalot.com
