The ISS is not in good shape:

"Superficial fissures have been found in some places on the Zarya module," Vladimir Solovyov, chief engineer of rocket and space corporation Energia, told RIA news agency. "This is bad and suggests that the fissures will begin to spread over time....

...The space station has suffered several recent incidents. Russian officials last month said a software glitch, and a possible lapse in human attention, were to blame for throwing the ISS out of control...

...The Russian space agency, Roscosmos, has said it will remain part of the ISS until 2024 and that it is open to extending its participation beyond then.
So, there was some news that scientists possibly created a small warp bubble in the lab, and the paper is currently being peer reviewed.

The issue is that system uses Casimir effect to achieve negative energy pressure and this cannot be used for any sort of propulsion.

There's stuff called virtual particles, defined by wiki as

A virtual particle is a transient quantum fluctuation that exhibits some of the characteristics of an ordinary particle, while having its existence limited by the uncertainty principle.[vague] The concept of virtual particles arises in perturbation theory of quantum field theory where interactions between ordinary particles are described in terms of exchanges of virtual particles

For this example virtual particles are the manifestation of energy change in the fabric of space. Any piece of space, up there somewhere or around you, inside you, fluctuates and these particles get 'spawned' all the time.

Energy pressure, specifically negative energy pressure, would mean that a quanta of space contains less energy than normal. Although this is counter intuitive when thinking about massive solid objects such as humans or ships (you have permanent mass - energy), taking it on a micro scale where there's nothing but virtual particles coming in and out of existence, means there's no source of energy in that piece of space than those particles themselves. It is the normal energy level of nothing, of emptiness, but it exists in quantifiable terms.

Manipulating that energy level would create a difference between the system and the surrounding - introducing pressure difference in space itself, moving that particular piece throughout fabric of space without its content ever experiencing any classical force.

Casimir effect is the effect of two rather large parallel metal plates separated by miniscule length, where they start attracting eachother without any additional force involved. The plates are actually being pushed into eachother by the outside environment.

Simplified - if the hole between plates is less than wavelength of a virtual particle the virtual particle can't spawn in that space. Meaning we're lowering the energy density of vacuum.

So why not warp drive based on rather old and well understood effect? Well the in between giant plates thing. Also to have 'warp geometry' we would need to move that plates.

The trick here is to have a self hosting system, e.g. an onboard propulsion. We can create all sorts of weird space-time effects inside cyclotrons and nuclear explosions and all the rest of high energy physics stuff but it's not applicable.
Blue Origin already got to the Karman Line and Musk already put space tourists in orbit.

Russians have been putting Tourists in space for decades. I meant in the context of their END goals. Musk wants to go to Mars, Bezos to the Moon. Branson just wanted to do this... Space Tourism, aaaand... he just did. Again, I understand both Bezos and Musk have WAY more logistical obstacles and deadlines, but hey, One down, two to go.
